Zero Mini Development Board
Overview
ESP32-S3-Zero (without pin header) and ESP32-S3-Zero-M (with pin header) are tiny in size with castellated holes, making them easy to integrate into other host boards. ESP32-S3-Zero comes with an onboard Type-C USB connector, which exposes most of the unused pins in a small form factor. It is equipped with the ESP32-FH4R2 chip, integrated Wi-Fi and BLE5.0, featuring 4MB Flash and 2MB PSRAM. In addition, there are hardware encryption accelerator, RNG, HMAC and Digital Signature modules to meet the safety requirements of IoT and provide rich peripheral interfaces. Moreover, its multiple low-power working modes support most application scenarios such as IoT, mobile devices, wearable electronic devices, and smart homes.
Features
- Equipped with Xtensa® 32-bit LX7 dual-core processor, up to 240MHz main frequency
- Supports 2.4GHz Wi-Fi (802.11 b/g/n) and Bluetooth® 5 (LE)
- Built in 512KB of SRAM and 384KB ROM, onboard 4MB Flash memory and 2MB PSRAM
- Castellated module and onboard ceramic antenna, allows soldering direct to carrier boards
- Supports flexible clock, module power supply independent setting, and other controls to realize low power consumption in different scenarios
- Integrated with USB serial port full-speed controller, 24 × GPIO pins allows flexibly configuring pin functions
- 4 × SPI, 2 × I2C, 3 × UART, 2 × I2S, 2 × ADC, etc.
Specifications
- When using ESP32-S3-Zero with daughterboards, please avoid covering the ceramic antenna with PCB boards, metal, or plastic components.
- In ESP32-S3-Zero, GPIO33 to GPIO37 pins are not exposed; these pins are used for Octal PSRAM.
- ESP32-S3-Zero uses GPIO21 to connect with WS2812 RGB LED. Please refer to this link for WS2812 specifications.
- ESP32-S3-Zero does not employ a USB to UART chip. When flashing firmware, press and hold the BOOT button (GPIO0) and then connect the Type-C cable.
- The "TX" and "RX" markings on the board indicate the default UART0 pins for ESP32-S3-Zero. Specifically, TX is GPIO43, and RX is GPIO44.

Funny detail
I love the watch, I have been using it for almost a year and didn’t have any kind of problem, I literally love it, but today I just find out the number 4 in roman numerals is not well written instead of IV is IIII, this detail makes me love it more since it give me some laughs.
