2.4. Evaluation Board

To help customers to develop applications with FC80A, Quectel supplies an evaluation board

(UMTS&LTE EVB), an RS-232 to USB converter cable, a USB data cable, a power adapter, antennas

and other peripherals to control or test the module. For details, see

document [1]

Dedicated Bluetooth antenna (ANT_BT) is optional according to the order code of the module.
