HC-08 Bluetooth DIP 4 pins
HC-08 Bluetooth Serial communication module It is a new generation.Be based on Specification V4.0 BLE Bluetooth protocol Data transfer module. Radio frequency band ISM 2.4GHz, the modulation method is GFSK. Module maximum transmit power is 4DBm, receiving sensitivity-93DBm,Under open environment and Iphone4s Can realize 80 Meter ultra long distance communication.
The module adopts stamp hole package, which can be used for welding.26.9mm*13mm*2.2mm, it is very convenient for customers to embed the application system.
