Description HM-10, JDY-08 Compatible This is the mini demo (or development) board for EB-08, suffix D for demo board. Firmware compatible with HM-10, but the original EY-08 firmware maybe better. Also fully compatible with JDY-08, information please google. We documented and updated documents in our wiki page, but for customer only. For EY-08 module please search in store. Board Features: 4x pins for GPIO1, 2, 3, 4. IO1 is connected to on board LED via jumper. 4x PWM pins PWM 2 is to mosfet control of mini motor PWM 1, 3, 4 to on board RGB LED, PWM 1, 3, 4 via jumpers (on middle pins). On back side 3.3V regulator, reset button, and CH340 USB-TTL USB debugger. 1x Power LED – on board front – left – top 1x Status LED and pin – next to power LED, when connection established, turn off (vice verse control by AT commands) 1x iBeacon Boardcasting LED and pin – indicting the broadcasting status, when connection established will be OFF. 1x Wake up pin, when send comands to turn it to sleep, this can wake up by external MCU. Serial UART interface on bottom right side – GND TXD RXD, VDD. To connector Motor: Notice when running motor, the interference will break the CH340 USB-TTL connection, but not bluetooth. If you use USB debugging, please notice this. External Motor power supply to VMOT and GND pin. Motor connect to VMOT and next pin PWM (which is PWM2). Demo video please see on this page.
