Carambola 3
The Carambola3 is a System on Module (SoM) based on the Qualcomm QCA4531 chipset. It is pin-to-pin compatible with the Carambola2 module, meaning that it has the same physical dimensions and pinout as the Carambola2. This allows for easy integration of the Carambola3 into existing systems that use the Carambola2 module.
