Cost effective Onmicro HS6621CM BLE 5 module RC6621A

The RC6621A is a powerful, compact size, cost-effective, low-power Bluetooth low energy (BLE 5) module based on the HS6621CM SoC from Onmicro Semiconductor. With an ARM^® Cortex™-M4FCPU, embedded with a 2.4 GHz transceiver, and integrated antenna, the RC6621A provides a complete RF solution with no additional RF design, allowing faster time-to-market.
Providing rich peripheral IOs, including 8 channels DMA, 2 UART interface, 1 I²S interface, 13 GPIOs, 2 SPI master or slave interface, 2 I²C master or slave interface, 3 32-bit timers, 3-way QDEC, etc.
The RC6621A can power most applications, simplifying designs and reducing BOM costs.
The RC6621A supports BLE 5 and is preprogrammed with easy-to-use transparent transmission firmware with AT commands.
