SPNYEM-52832-P01 is powerful, highly flexible, ultra-low power Bluetooth Low Energy 4.2 (BLE 4.2) module using Nordic nRF52832 SoCs. It was designed for high data rate, short-range wireless communication in the 2.4GHz ISM band. With an ARM CortexTM M4F MCU, available 512KB flash, 64KB RAM, embedded 2.4GHz multi-protocol transceiver, power amplifier, and an integrated 2.4GHz Mini antenna The SPNYEM-52832-P01 is a 13.8 mm× 21 mm module. It is a compact and very small size module with optional antenna types; PCB antenna and Chip antenna. It allows developers to take full advantage of the nRF52832 by making all its I/O available via 34 SMD 1.2mm pitch pads.
