Adafruit NRF52840 Feather Express
This board enables connecting buttons, switches, encoders, potentiometers, rotary switches, joysticks and various sensors, to easily deploy wireless solutions.
An battery charging circuit allows you to power the board with a battery for embedded applications, along with an internal connexion in order to measure precisely the battery voltage, so you will know the charge that's left.
You will have access to 22 I/Os, including 7 analog inputs with a 12 bits ADC. One additionnal digital input is available for the on board user switch, as well as an "NFC" pad under the board if another input is needed. The inputs are 3.3 V and are not 5 V tolerant. The heart of this board is the NRF52840, the most suitable microcontroller on the market for embedded systems. Clocked at 64 MHz, it also offers 2 SPI ports, 1 I2C port , and 1 serial port. Like all the boards we propose, we have enhenced the kernel in order to offer as much features as possible.
Note : This board is not using the bluetooth protocol, you will have to use a NrfDongle dongle to make it use it.

ElectroSeed SamD21 WB Radio
The ElectroSeed SamD21 WB Radio board offers 31 inputs/outputs, including 14 analog inputs. 4 analog inputs have pull-up resistors, which allows direct connection of bodacs, thus adding the possibility of connecting 20 additional buttons.
5v power is available (if powered from a Moza or Simagic or other QR providing 5v) around the serial port to connect a Nextion screen or a 7-segment display. The 5v is also exposed to connect RGB leds. Screen and leds are managed with SimHub software, and requires an NRF Dongle to communicate with the PC.
Attention : this card is intended for use with a Moza, Simagic base or other system with induction power supply providing 5V. For use with battery, you will need to go to another card managing battery charging (Feather or XIAO Ble), or a card equipped with a 5V booster to power a screen or many LEDs (MMWB)
The following connectors are also proposed :
- A 5v power connector to connect to the Simagic or Moza bases (thanks to our Simagic and Moza Quick Releases), the radio version allowing native radio communication with Simagic bases (inputs only, 32 functions) or with Moza bases (inputs only, 64 functions)
- A 4-pin JST 2.0 connector to easily connect an aviation connector or a panel mount USB connector for firmware updates.
- A USB-C connector to program the board or connect a USB extension.
If you choose a customized firmware option, a NodeBlue package will be included with the board, so you can have any configuration you need. A configuration form will be sent after your order, so you can specify the desired programming. The board will be programmed accordingly and the wiring schematics will be provided. You can check here if your configuration is possible.

Seeed Studio XIAO BLE
The Seeeduino XIAO BLE board brings you the power of a nRF52840 in one of the smallest form factor, and allows to deploy wireless projects at a small cost. It includes a Texas Instrument BQ24101 battery charging circuit, and the battery charge level can be measured.
Thanks to Node Blue, this board enables connecting buttons, switches, encoders, potentiometers, rotary switches, joysticks and various sensors.
Attention, this board uses an USB-C connector.
