ESP32-SL specification V1.0 6.DESIGN GUIDE 1、Application circuit 2. Antenna layout requirements (1) The following two methods are recommended for the installation location on the motherboard: Option 1: Place the module on the edge of the main board, and the antenna area protrudes from the edge of the main board. Option 2: Place the module on the edge of the motherboard, and the edge of the motherboard digs out an area at the position of the antenna.

ESP32-SL specification V1.0 4. Use of GPIO port (1) Some GPIO ports are led out of the periphery of the module. If you need to use a 10-100 ohm resistor in series with the IO port is recommended. This can suppress overshoot, and the level on both sides is more stable. Help both EMI and ESD. (2) For the up and down of the special IO port, please refer to the instruction manual of the specification, which will affect the startup configuration of the module. (3) The IO port of the module is 3.3V.
