The 433mHz AM beacon was updated. The Atmel 328p now has its own PCB instead of the “legs-up-beetle” style of previous versions. The further reduce the size of the unit, the 328p board was placed in a sandwich orientation with the transmitter module.
Despite the small size, the board now has a programming port to enable reprogramming of the module.
