Chapter 1. Get Started
Power Supply Options
• USB-to-UART Port and ESP32-S2 USB Port (either one or both), default power supply (recommended)
• 5V and G (GND) pins
• 3V3 and G (GND) pins
Header Block The two tables below provide the Name and Function of the pin headers on both sides of the board
(J1 and J3). The pin header names are shown in
