## Description

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 same Raytac MDBT50Q-P1M found on our [Pro nRF52840 Mini](https://core-electronics.com.au/search/?q=15025?_ga=2.250420870.1636744795.1610382737-881909304.1580318117). This module includes an integrated trace antenna, fits the IC to an FCC-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.

We've also routed 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.

*[MicroMod](https://www.sparkfun.com/micromod) is a modular interface ecosystem that connects a microcontroller “processor board” to various “carrier board” peripherals. Utilizing the M.2 standard, the MicroMod standard is designed to easily swap out processors on the fly. Pair a specialized carrier board for the project you need with your choice of compatible processor!*

**nRF52840 General Features**:

- ARM Cortex-M4 CPU with floating point unit (FPU) 
    - 1MB internal Flash -- For all of your program, SoftDevice, and file-storage needs!
    - 256kB internal RAM -- For your stack and heap storage.
- Integrated 2.4GHz radio with support for: 
    - Bluetooth Low Energy (BLE) -- With peripheral and/or central BLE device support
    - Bluetooth 5 -- Mesh Bluetooth!
    - ANT -- If you want to turn the device into a heart-rate or exercise monitor.
    - Nordic's proprietary RF protocol -- If you want to communicate, securely, with other Nordic devices.
- Every I/O peripheral you could need 
    - USB -- Turn your nRF52840 into a USB mass-storage device, use a CDC (USB serial) interface, and more. This is a big add compared to the [nRF52832](https://core-electronics.com.au/search/?q=13990)!
    - UART -- Serial interfaces with support for hardware flow-control if desired.
    - I2C -- Everyone's favorite 2-wire bi-directional bus interface
    - SPI -- If you prefer the 3 -wire serial interface
    - Analog-to-digital converters (ADC) -- Eight pins on the nRF52840 Mini Breakout support analog inputs
    - PWM -- Timer support on any pin means PWM support for driving LEDs or servo motors.
    - Real-time clock (RTC) -- Keep close track of seconds and milliseconds, also supports timed deep-sleep features.
