ESP32-S2-WROVER User Manual V0.1
Note:
• Soldering the EPAD to the ground of the base board is not a must, though doing so can get optimized thermal
performance. If users do want to solder it, they need to ensure that the correct quantity of soldering paste is applied.
• To ensure the power supply to the ESP32-S2 chip 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 = 0.1 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. For ESP32-S2’s power-up and reset sequence timing diagram, please refer to Section Power
Scheme in ESP32-S2 Datasheet.
