- May 10, 2019-

If you are in development phase and need very simple BT module with SPP and URAT and HC-06 is one of the option which might fit.


But you may find that HC-06 size 27*13*2 mm , it is a little big ,and you prefer small size module , we are glad to recommend a small size module ,BT821 .V4.2 Dual Mode ,it is ultra small size :15*12*2.0mm ,and dual mode support SPP/GATT .
