Preliminary pre-release version 2022-05-06
This is an preliminary pre-release datasheet and the contents are subject to change.
The E404X is a LTE Cat M1 cellular device with support for BLE (Bluetooth LE). It is based on the Nordic nRF52840 microcontroller shared with other Gen 3 devices such as the Boron and B Series SoM. It is only intended for use in the United States, Canada, and Mexico.
It is a SMD module designed to be reflowed to your own custom base board and is the same size and has a nearly identical pin-out to the E Series module.
If you are migrating from the E402 or E404, there is a migration guide available.
There will not be 2G/3G "X" version E Series; there will not be an E310X or E314X.
New designs should use the B404X (B Series SoM) instead of the E404X.

The E series can be powered via the VIN (3.88V-12VDC) pin, over USB, or a LiPo battery.
The input voltage range on VIN pin is 3.88VDC to 12VDC. When powering from the VIN pin alone, make sure that the power supply is rated at 10W (for example 5 VDC at 2 Amp). If the power source is unable to meet this requirement, you'll need connect the LiPo battery as well. An additional bulk capacitance of 470uF to 1000uF should be added to the VIN input when the LiPo Battery is disconnected. The amount of capacitance required will depend on the ability of the power supply to deliver peak currents to the cellular modem.
The E404X can be powered with as little as 550 mA at 5V.
This pin serves two purposes. You can use this pin to connect a LiPo battery directly without having to use a JST connector or it can be used to connect an external DC power source (and this is where one needs to take extra precautions). When powering it from an external regulated DC source, the recommended input voltage range on this pin is between 3.6V to 4.4VDC. Make sure that the supply can handle currents of at least 3Amp. This is the most efficient way of powering the E series since the PMIC by-passes the regulator and supplies power to the E series module via an internal FET leading to lower quiescent current.
When powered from a LiPo battery alone, the power management IC switches off the internal regulator and supplies power to the system directly from the battery. This reduces the conduction losses and maximizes battery run time. The battery provided with the E series module is a Lithium-Ion Polymer battery rated at 3.7VDC 1,800mAh. You can substitute this battery with another 3.7V LiPo with higher current rating. Remember to never exceed this voltage rating and always pay attention to the polarity of the connector.
Typical current consumption is around 180mA and up to 1.8A transients at 5VDC. In deep sleep mode, the quiescent current is 130uA (powered from the battery alone).
This pin is internally connected to USB supply rail and will output 5V when the E series module is plugged into an USB port. It is intentionally left unpopulated. This pin will NOT output any voltage when the E series module is powered via VIN and/or the LiPo battery.
Most USB ports can supply only a maximum of 500mA, but the u-Blox GSM module on the E series alone can consume a peak of 800mA to 1800mA (2G/3G) or 550 mA (LTE Cat M1) of current during transmission. In order to compensate of this deficit, one must connect the LiPo battery at all times when powering from a traditional USB port for 2G/3G. The E series will intelligently source power from the USB most of the time and keep the battery charged. During peak current requirements, the additional power will be sourced from the battery. This reduces the charge-discharge cycle load on the battery, thus improving its longevity.
This pin is the output of the on-board 3.3V switching regulator that powers the microcontroller and the peripherals. This pin can be used as a 3.3V power source with a max load of 800mA. Unlike the Photon or the Core, this pin CANNOT be used as an input to power the E series module.
This is the supply to the internal RTC, backup registers and SRAM. You can connect a backup battery to it (1.65 to 3.6VDC), if you wish to retain RTC/RAM when 3V3 is absent or simply tie it up to 3V3.
This pin in subject to change depending on the PMIC that is selected for the E404X.
This pin is the output of the internal boost regulator of the PMIC that can source 5.1VDC from the battery in OTG (On The Go) mode. This feature is useful when your circuitry needs a 5V source from the E series module when powered by the battery alone.
The confusing bit about this pin is that it will continue to provide 5.1VDC but only when the input voltage (VIN) is between 3.6V to 5.1VDC. As soon as the input voltage exceeds this limit, the PMID starts tracking that voltage. For example if VIN = 9VDC, the PMID will be 9VDC and NOT 5.1VDC. So you need to be careful when using it as a source for powering your external circuitry. The max current draw on this pin is 2.1A but is not recommended due to thermal limitations of the circuit board.

The E404X does not have a BLE chip antenna on the module and requires an external antenna if BLE is to be used. Using BLE on the E404X is optional, and the antenna is not required if BLE is not used.
The Particle 2.4 GHz BLE antenna is available in the retail and wholesale stores. Note: The same external antenna model is used for Wi-Fi and BLE.

- The antenna placement needs to follow some basic rules, as any antenna is sensitive to its environment. Mount the antenna at least 10mm from metal components or surfaces, ideally 20mm for best radiation efficiency, and try to maintain a minimum of three directions free from obstructions to be able to operate effectively.
- Needs tuning with actual product enclosure and all components.
- For the BLE antenna, it is recommended to use a 2.4 GHz single-frequency antenna and not a 2.4 GHz + 5 GHz antenna, so as to avoid large gain at the frequency twice of 2.4 GHz which can cause the second harmonic radiation of 2.4 GHz to exceed standards.
|Peripheral Type||Qty||Input(I) / Output(O)|
|Analog (ADC)||8 (max)||I|
- GPIO is limited to 3.3V maximum (not 5V tolerant)
- If an alternate port such as SPI or Serial is not being used for that purpose, the pins can generally be used as GPIO

The E404X supports 8 ADC inputs.
|Pin||E404X Pin Name||E404X ADC|
|19||A7 / WKP||ADC7|
- ADC inputs are single-ended and limited to 0 to 3.3V
- Resolution is 12 bits
On the B404X, BRN404X, and E404X, the ADC reference is the nRF52840 internal 0.6V reference, with a 1/6 gain from the input pin. This is different than other Gen 3 devices which use 3V3 as the ADC reference.
This reference and gain combination is a range of 0 to 3.6V for 0 - 4095. This is scaled in software so 3.3V will still be 4095, so there will be a slight loss of resolution.
- One available hardware UART (
- Supported baud rates: 1200, 2400, 4800, 9600, 19200, 28800, 38400, 57600, 76800, 115200, 230400, 250000, 460800, 921600 and 1000000.
Configuration options include:
SERIAL_8N1- 8 data bits, no parity, 1 stop bit (default)
SERIAL_8E1- 8 data bits, even parity, 1 stop bit
Other options, including odd parity, and 7 and 9 bit modes, are not available on the E404x or Gen 3 devices.
Flow control is available on Serial1 D3(CTS) and D2(RTS). If you are not using flow control (the default), then these pins can be used as regular GPIO.
SERIAL_FLOW_CONTROL_NONE- no flow control
SERIAL_FLOW_CONTROL_RTS- RTS flow control
SERIAL_FLOW_CONTROL_CTS- CTS flow control
SERIAL_FLOW_CONTROL_RTS_CTS- RTS/CTS flow control
|Pin||E404X Pin Name||E404X UART|
- Any available GPIO can be used for SPI chip select (SS).
- Generally speaking, multiple SPI devices can share a SPI bus, however the software library must enable it using SPI transactions

On the E404X, the following groups are defined. Each group must share the same frequency and resolution, but individual pins in the group can have a different duty cycle. Group 0 is shared with the RGB LED and must use the default resolution of 8 bits (0-255) and frequency of 500 Hz, but can have its own duty cycle.
- Group 0: C5, RGBB, RGBG, RGBR
- Group 1: A3, C0, D0, D1, D2
- Group 2: B2, B3, RX, TX
- Group 3: A4, A5, A6, C4

 A fault condition can occur due to several reasons, for example, battery over/under voltage, temperature fault or safety timer fault. You can find the root cause by reading the fault register of the power management IC in firmware.
 You can stop this behavior by either plugging in the LiPo battery or by disabling the charging using the appropriate firmware command.

The E series contains highly sensitive electronic circuitry and is an Electrostatic Sensitive Device (ESD). Handling an E series without proper ESD protection may destroy or damage it permanently. Proper ESD handling and packaging procedures must be applied throughout the processing, handling and operation of any application that incorporates EØs. ESD precautions should be implemented on the application board where the E series is mounted. Failure to observe these precautions can result in severe damage to the E series!
The U.FL antenna connectors are not designed to be constantly plugged and unplugged. The antenna pin is static sensitive and you can destroy the radio with improper handling. A tiny dab of glue (epoxy, liquid tape or hot glue) on the connector can be used securely hold the plug in place.
The E series comes pre-programmed with a bootloader and a user application called Tinker. This application works with an iOS and Android app also named Tinker that allows you to very easily toggle digital pins, take analog and digital readings and drive variable PWM outputs.
The bootloader allows you to easily update the user application via several different methods, USB, OTA, Serial Y-Modem, and also internally via the Factory Reset procedure. All of these methods have multiple tools associated with them as well.
You may use the Particle Web IDE to code, compile and flash a user application OTA (Over The Air). Particle Workbench is a full-featured desktop IDE for Windows, Mac, and Linux based on VSCode and supports both cloud-based and local gcc-arm compiles. The Particle CLI provides a command-line interface for cloud-based compiles and flashing code over USB.
