Had some initial wiring confusion
The pinout wasn't clearly marked on the board itself. Had to check the schematic online. Works fine now but could be more user-friendly.

Good value but docs need work
Hardware is solid and handles the current well. However, the documentation could be more detailed for beginners. Once set up, it works great.
Q: What is the effective Bluetooth range?
A: The effective range is approximately 10 meters in an open environment. Obstacles may reduce this distance.
Q: What voltage range does this controller support?
A: The controller supports an input voltage range of 5V to 12V DC. Please ensure your power supply matches this specification.
Q: Does it work with analog servos or only digital?
A: It supports both analog and digital servos. You can configure the PWM signals via firmware to match your specific servo type.
Q: Are there code libraries available for ESP32?
A: Yes, we host libraries on our GitHub repository. Search for Haner Servo Controller to find examples compatible with the Arduino IDE.
Q: Can I chain multiple boards together for more channels?
A: Yes, multiple boards can be daisy-chained using the UART interface to expand the total number of servo channels.
