Shanghai RaymonIoT Technology Co., Ltd.

7.1. UART TTL Voltage Transform

7.2. Transsistor Transform (Recommend)

If the RX pin of the user equipment considers 3.3V to be high, it can be directly connected. No need of the

Transform circuit.

7.3. Resistor Divider (Low Cost Solution)

If the RX pin of the user equipment considers 3.3V to be high, R1, R3, and D2 can be removed.

7.4. MOSFET

The most stable version of the hardware supports high-speed transmission (baud rate 921600, etc.), but

at a higher cost.
