Datasheet - MDBT50Q ModuleProduct Overview
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. 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.

Features & Specs
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!
- 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.
