India 2.5K FSC-BT826E HC05 compatible module, low cost but dual mode.
Thanks for customer's support as always.
FSC-BT826E(HC 05 Pin to pin) version, turn outs to be the best module to replace the old and low version hc05 in the market.
HC05 only v2.1 and can not pass certification. If your bluetooth end products enter the world wide market, we must get certification. Only bluetooth 4.2 and above products can pass certification.
