Nordic nRF52840 BLE Module (MDBT50Q-1MV2)

MDBT50Q-1M nRF52840 Based BLE Module

nRF52840-based BLE 5.0 module with peripheral interfaces including GPIO, SPI, UART, I2C, I2S, PWM, ADC, NFC and USB. Treat as an embeddable module, not a plug-in carrier.

MDBT50Q-P1M nRF52840 Based BLE Module

Related nRF52840-based BLE 5.0 module variant. Likely same broad silicon family as MDBT50Q-1M, but antenna/package and layout details still need exact-page checks.

Bluetooth 4.0 Low Energy - BLE Mini

Older Bluetooth 4.0 Low Energy Mini board. Useful as a BLE breakout/prototype board, not a drop-in replacement for an nRF52840 module.

Bluetooth 4.0 Motherboard

BLE 4.0 2.4 GHz motherboard/development carrier with I/O expansion connectors and multiple interfaces. A support board, not a compact BLE module.

nRF52840 Bluetooth® Low Energy Module with USB

nRF52840 BLE module with USB support. Same broad Nordic BLE family as MDBT50Q-style modules, but footprint, antenna, bootloader and certification details must be checked before substitution.

nRF52832 Bluetooth® Low Energy Module

nRF52832 BLE module. Same broad Nordic BLE direction as nRF52840 modules, but lower/different silicon family and not a blind drop-in replacement.

Adafruit Bluefruit LE UART Friend - Bluetooth® Low Energy

Bluefruit LE UART Friend. Useful when the design wants a UART-connected BLE breakout; not interchangeable with SPI, USB dongle or bare module formats without wiring/firmware review.

Adafruit Bluefruit LE SPI Friend - Bluetooth® Low Energy

Bluefruit LE SPI Friend. BLE breakout for SPI-connected designs; not a drop-in for UART Bluefruit or bare nRF52 modules.

Adafruit Bluefruit LE Shield - Bluetooth® LE for Arduino

Bluefruit LE Shield for Arduino. Arduino shield form factor; convenient for compatible Arduino boards, but mechanically different from compact BLE modules and friends.

Bluno Bee - Turn Arduino to a Bluetooth 4.0 (BLE) Ready Board

Bluno Bee BLE board for XBee-style sockets and Arduino workflows. Treat as a carrier/module class, not a direct substitute for bare BLE modules.

Bluetooth V4.0 HM-11 BLE Module - Seeed Studio

HM-11 Bluetooth 4.0 BLE module. Older BLE module class; compare UART/AT firmware, voltage and pinout before replacing Bluefruit or nRF52 modules.

Beetle BLE - The smallest Arduino Bluetooth 4.0 (BLE)

Arduino-compatible Bluetooth 4.0 BLE board based on the DFRobot Beetle BLE listing. Useful as a tiny controller board, not a replacement for bare nRF52 modules or USB/SPI/UART bridge boards.

Seeed Studio XIAO nRF52840

XIAO-format nRF52840 BLE dev board with onboard antenna and battery-charging support. Related to nRF52840 module designs, but the XIAO pinout, bootloader and board hardware make it a board-level redesign.

Seeed Studio XIAO nRF52840 Sense

XIAO nRF52840 Sense adds onboard sensing hardware such as microphone and 6-axis IMU. Treat it as a tinyML/sensing dev board, not the same part as the base XIAO nRF52840.

XIAO MG24 - Matter Native over Thread / BLE 5.3

XIAO MG24 board for Matter-native over Thread plus BLE 5.3 designs. It belongs in the XIAO wireless dev-board family but is not firmware-equivalent to nRF52840 BLE boards.

XIAO MG24 Sense - Matter Native over Thread / BLE 5.3

XIAO MG24 Sense variant for Matter/Thread/BLE designs with extra onboard sensing. Similar board outline to MG24, but sensor payload and firmware target still need exact-design review.

Seeed Tiny BLE - BLE + 6DOF Mbed Platform

Tiny BLE / nRF51822-era BLE plus 6DOF mbed platform board. Treat as a legacy dev-board option, not a drop-in for nRF52840 or MG24 wireless platforms.

Bluefruit LE Sniffer - Bluetooth Low Energy (BLE 4.0) - nRF51822 - Firmware Version 2

Bluefruit LE Sniffer for Bluetooth Low Energy packet inspection and debugging. Do not substitute it for an application BLE module or bridge board.

Bluefruit LE Friend - Bluetooth Low Energy (BLE 4.0) - nRF51822 - v3.0

Bluefruit LE Friend is a USB-to-BLE bridge-style board. Useful for computer-to-BLE workflows, but not interchangeable with UART Friend, SPI Friend or embedded radio modules without interface changes.
