ESP32-S3 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 adopts ESP32-FH4R2 as a System-on-Chip (SoC) that integrates low-power WiFi and BLE5.0 with 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 low-power working mode supports most application scenarios such as IoT, mobile devices, wearable electronic devices, and smart homes.
Features
- quipped 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, allow 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 allow flexible configuring pin functions.
- 4 × SPI, 2 × I2C, 3 × UART, 2 × I2S, 2 × ADC, etc.
Hardware Description
- 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.
Hardware Connection
- Press the BOOT (GPIO0) key before connecting the Type-C cable each time download the firmware.
- Input 3.7V~6V for the castellated hole with 5V silkscreen when connecting the external power.

Works for dry mouth
Suffer from dry mouth and these disc size tablets stick to my gums, helping keep my mouth moist through the night. Brown side sticks to your gum. Contain xylitol so s little sweet. Dentist recommended them.

PRICEY and sometimes don’t stay in place!
These have a wonderful mild flavor, no mint burn, moisten your mouth for several hours, and generally always stay put, in fact if you want it out before fully dissolved, it takes a little effort with your fingernail, because they are supposed to stick and stay in place! ALSO, I DO NOT PUT ON MY GUMLINE LIKE THE INSTRUCTIONS SAY, I STICK ON THE ROOF OF MY MOUTH FOR DISCREET CONFORT!!
I really do recommend for DRY MOUTH!! I DO NOT CARE FOR THE SHARP EDGY METAL INDIVIDUAL PACKAGING AT ALL, but the bottle is very pricey!!

Absolutely work!
These are absolutely fantastic. Bygone are the days of sucking on some sugary sweet Candy. Xylo melts stick as they say they do. I have found that they don't stick to artificial teeth as well. They last for hours they're comfortable. The mint ones aren't overpowering. These are a dry mouth blessing. For sure use them at night and during the day.

Invaluable sleep/ dry mouth aid
Cannot live even one night without these Xylimelts. Taste great. Stick well to mouth. Remember: poisonous to dogs. Now we have a dog so I no longer buy the bottles of loose melts as I can spill in middle of night and lose track. Extremely nerve wracking. Using the sheets of melts which you punch out one at a time. Easier to insure dog’s safety.

They may have saved my life!
These are fantastic for people with dry mouth! They have been a lifesaver for me. I HIGHLY recommend them to everyone! I carry them in my bag as well. Thanks to the one who invented them. I feel normal again!!! Easy to pop in mouth and they last overnight too.
