Si24R1 Dev Board – Ai Thinker NF-01-S

Compact dev board for the Si24R1 2.4GHz RF transceiver chip – a cheaper alternative to Nordic’s popular nRF24L01 . Looking to compete directly with Nordic, the Si24R1 is also an ultra low power (ULP) 2Mbps RF transceiver IC for the 2.4GHz band with many similar specs and features.
