Nordic nRF52840 BLE Module (MDBT50Q-1MV2)

Raytac’s MDBT50Q is a BT 5.2 stack (Bluetooth® low energy or BLE) module designed based on Nordic nRF52840 SoC solution, which incorporates: GPIO, SPI, UART, I2C, I2S, PMD, PWM, ADC, NFC and USB interfaces for connecting peripherals and sensors.

It features an embedded 2.4GHz transceiver supports Bluetooth 5.2, IEEE 802.15.4 (Thread & Zigbee) & 2.4Ghz RF & ANT+ upon customer’s preference. Compact size with (L) 15.5 x (W) 10.5 x (H) 2.05 or 2 mm. Low power requirements, ultra-low peak, average and idle mode power consumption. Fully coverage of BLE software stack. BLE & RF transmission switching helps products fit all operation system and most hardware
