## 6 Design Guidance 

## 6.1. Note ： 

- （ 1 ） When GPIO20 is used as U1RXD, a pull-up resistor needs to be added externally. 

- 6.2. Antenna layout requirements 

- （ 1 ） For the installation position on the motherboard, the following two methods are 

recommended ： 

Solution 1: Put the module on the edge of the main board, and the antenna area extends out of the edge of the main board. 

Solution 2: Put the module on the edge of the main board, and hollow out an area at the antenna position on the edge of the main board. 

（ 2 ） In order to meet the performance of the on-board antenna, metal parts are forbidden to be placed around the antenna, away from high frequency devices. 

## 6.3. Power supply 

- (1) Recommend 3.3V voltage, peak current above 500mA 

(2) It is recommended to use LDO for power supply; if DC-DC is used, the ripple is recommended to be controlled within 30mV. 

(3) DC-DC the power supply circuit, it is suggested to reserve the position of output ripple can be optimized when the load changes greatly. 

- (4) It is recommended to add ESD devices to the 3.3V power interface.

## ESP-C3-12F 

## 6.4. GPIO Interface 

(1) The module periphery leads to some GPIO ports, such as the recommended resistance of 10-100 Ohms in series on the IO port. This can suppress overshoot, to ensure both sides of the level more stable. helpful for both EMI and ESD. 

(2) For special IO, please refer to the specification, which will affect the starting configuration of the module. 

(3) The IO port of the module voltage is 3.3 V, if the main control does not match the IO level of the module, require to add the level conversion circuit. 

(4) When the IO port is connected directly to the peripheral interface, or the pin header and other terminals, it is recommended to reserve ESD device near the terminal.
