BLE Micro EVB - Bluetooth 4.0 Device

MDBT50Q-P1M nRF52840 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 NRF51822 Motherboard (BLE400)

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.

Nordic nRF52840 BLE Module (MDBT50Q-1MV2)

Raytac MDBT50Q-1MV2 nRF52840 BLE module from SparkFun. Related to other MDBT50Q/nRF52840 modules, but use the exact package and antenna variant from the source page.

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

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

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