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.

Works well!
Size: 8 Fl Oz (Pack of 1)
So far I like this! It is runnier than normal lotion so you don’t need as much. The only thing I don’t like it smells like baby powder to me. But it does work really well with tans!

Love this lotion!!!
Size: 4 Fl Oz (Pack of 1)
The first bottle I received had leaked all over the inside of the package but I sent that back and got a replacement. I love this lotion. I actually first purchased it while I was in Maui 10 years ago. I love the scent of it and it really moisturizes my skin after sunning.

Absolutely the best, no joke
We actually lived on Maui when we discovered Maui Babe, and have been using it ever since. Let me tell you: it is the BEST after sun lotion, bar none. Got a little over-exposed, and are red and hurting? Throw some Maui Babe on, and not only will it relieve the pain (and eventual itching) of sunburn, it'll help prevent peeling later on. It's great as an every day lotion, of course, but it really shines on sunburn. My husband and I laugh about steering many a sunburned tourist to the Maui Babe display in stores all over Hawaii. "Hey, you really need to get some of THIS for that burn." They always seemed grateful to get steered to something that really worked, instead of the usual lotions and potions that didn't. Anyway, I can highly recommend it, been using it for years, and as a blonde who has lived in Hawaii, southwest Florida, and now down in Panama (where the sun is damned close), I can tell you that it really works. And yes...my last order came all the way to Panama because I can't do without it.

Great product!
Style: Deep Moisturizing, Size: 1.76 Fl Oz (Pack of 1)
I love this stuff! My mom introduced this to me while I was visiting her, and within 3 days of using it I knew I needed to order one for myself. It has no smell, goes on buttery soft, and soaks in well. It is not heavy at all. At night I layer it on thicker and during the day I put a very thin layer on under my makeup. My skin is so much softer and hydrated. I have had small bumps on my cheeks for so long and they were gone within 3 days. My skin looks dewy and soft.
I read reviews of other brands that smelled, were oily, or too heavy. This is none of those things and it is a great price!
