ESP-12K Specification V1.0 6.DESIGN GUIDE 1、Application circuit note: (1) The RC delay circuit needs to be added to the EN pin. It is recommended that R = 10kΩ and C = 0.1μF; (2) GPIO18 as U1RXD needs to add a pull-up resistor externally. 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.
ESP-12K Specification V1.0 3、Power supply (1) 3.3V voltage is recommended, the peak current is more than 500mA (2) It is recommended to use LDO for power supply; if using DC-DC, it is recommended to control the ripple within 30mV. (3) It is recommended to reserve the position of the dynamic response capacitor in the DC-DC power supply circuit, which can optimize the output ripple when the load changes greatly. (4), 3.3V power interface is recommended to add ESD devices.
