5.4 Peripheral Schematic
This is the typical application circuit of the module connected with peripheral components (for example,
power supply, antenna, reset button, JTAG interface, and UART interface).
Figure 7 Application Circuit
Soldering the EPAD to the ground of the base board is not a must, though doing so can get
optimized thermal performance. If you do want to solder it, please ensure that you apply the correct
amount of soldering paste.
To ensure the power supply to the ESP32-C3 family chip is stable during power-up, it is advised
to add an RC delay circuit at the EN pin. The recommended setting for the RC delay circuit is usually
R = 10 kΩ and C = 1 µF. However, specific parameters should be adjusted based on the power-up
timing of the module and the power-up and reset sequence timing of the chip.
