Featuring the nRF52840 SoC from Nordic Semiconductor, the SparkFun MicroMod nRF52840 Processor offers a powerful combination of ARM Cortex-M4 CPU and 2.4 GHz Bluetooth transceiver in the MicroMod form-factor with the M.2 MicroMod connector to allow you to plug in a compatible MicroMod Carrier Board with any number of peripherals.

The MicroMod nRF52840 Processor features the Raytac MDBT50Q-P1. This module includes an integrated trace antenna, fits the IC to an FCC and CE approved footprint along with including decoupling and timing mechanisms that would need to be designed into a circuit using the bare nRF52840 IC. The Bluetooth transceiver included on the nRF52840 boasts a BT 5.1 stack and supports Bluetooth 5, Bluetooth mesh, IEEE 802.15.4 (Zigbee & Thread) and 2.4Ghz RF wireless protocols (including Nordic's proprietary RF protocol) allowing you to pick which option works best for your application.

There's also two I2C buses, 2 SPI buses, eleven GPIO, dedicated digital, analog, PWM & PDM pins along with multiple serial UARTS to cover nearly all of your peripheral needs.

We have fixed a hardware bug on this board in order to be able to use the ADC for radiometric measures (potentiometers, etc.).

With a 32-bit ARM Cortex-M0 MCU, the ElectroSee MicroMod SAMD21 Processor Board provides you with the highest numer of inputs/outputs in the Micromod familly. It also includes a USB hub, and exposes the secondary port on the USB host connexions of the Micromod standard. This hub is compatible with the USB 2.0 480 Mb/s High Speed standard, and allows to connect reliably USB screens like Vocore screens.

The microcontroler used is an ATSAMD21J18, a 32-bit ARM Cortex-M0, running at 48 MHz, has 256 KB of flash memory, 32 KB of SRAM, 6 SERCOM interfaces, and other features.

Number of inputs/outputs : 50 including 20 analog.
