OLIMEX ESP32-S3 LiPo Open Source Hardware Board Dev Kit User Manual
Introduction to ESP32-S3-DevKit-LiPo
ESP32-S3 is a dual-core XTensa LX7 MCU, capable of running at 240 MHz. Apart from its 512 KB of internal SRAM, it also comes with integrated 2.4 GHz, 802.11 b/g/n Wi-Fi and Bluetooth 5 (LE) connectivity that provides long-range support. It has 45 programmable GPIOs and supports a rich set of peripherals. ESP32-S3 supports larger, high-speed octal SPI flash, and PSRAM with configurable data and instruction cache.

ESP32-S3-DevKit-Lipo schematics:
ESP32-S3-DevKit-LiPo latest schematic is on GitHub
UEXT connector:
UEXT connector stands for Universal EXTension connector and contain +3.3V, GND, I2C, SPI, UART signals.
UEXT connector can be in different shapes.
The original UEXT connector is 0.1” 2.54mm step boxed plastic connector. All signals are with 3.3V levels.
UEXT Connector
note it share same pins with EXT1 and EXT2
As the boards become smaller and smaller some smaller packages were introduced too beside the original UEXT connector
- mUEXT is 1.27 mm step boxed header connector which is with same layout as UEXT
- pUEXT is 1.0 mm single row connector (this is the connector used in RP2040-PICO30)
Olimex has developed number of MODULES with this connector. There are temperature, humidity, pressure, magnetic field, light sensors. Modules with LCDs, LED matrix, Relays, Bluetooth, Zigbee, WiFi, GSM, GPS, RFID, RTC, EKG, sensors and etc.
