Compact ESP32 development board (dual-core 240 MHz) with 4 MB PSRAM, USB-C, 14 GPIO, onboard APA102 RGB LED, JST-PH LiPo connector, and a 700 mA 3.3V regulator. Deep-sleep current as low as 20 µA. Ships with MicroPython pre-installed.
USB-C connector for board power and USB-to-serial programming; Adafruit identifies this TinyPICO variant as the USB-C development board.
Board 5 V power path isolated from the 3.3 V path; powers USB-side circuitry when a 5 V source is present.
3.3 V regulated rail from the onboard 700 mA regulator; Adafruit states TinyPICO has a 700 mA 3.3 V regulator and a separate 3.3 V power path.
Board ground reference for power and GPIO connections.
General-purpose ESP32 I/O exposed by the TinyPICO board; Adafruit states the board exposes 14 GPIO.
Controls the high-side switch for power to the onboard APA102 RGB LED; Adafruit notes GPIO13 controls APA102 power through a P-channel MOSFET.
Battery-management connection/path for LiPo battery operation; product page states onboard battery management and separate battery/3.3 V operation.
