ProS3[D] is Unexpected Maker's NEW top-of-the-line Extremely Pro ESP32-S3 board! It's packed with amazing features and peripherals, ESD protection, castellated headers, wireless co nnectivity, and stacks of Flash and PSRAM, and it's TinyPICO/TinyS3[D] compatible! ProS3[D] combines the previous ProS3 and ProS3 uFL boards into a single board, giving you more options and no need to pick one or the other. It also replaces the VBAT ADC sense pin with an I2C battery fuel gauge. ProS3[D] has full drop-in compatibility with the previous ProS3 versions, but Unexpected Maker did need to extend the board length by 2mm to fit everything in and still allow for a solid, well-tuned RF layout. Features Dual 32bit Xtensa LX7 cores @ up to 240Mhz RISC-V Ultra Low Power Co-processor 2.4GHz Wifi - 802.11b/g/n Bluetooth LE 5 + Mesh 16MB QSPI Flash 8MB of extra QSPI PSRAM 2x 700mA 3.3V LDO Regulators LDO2 is user controlled & auto-shuts down in deep-sleep Low power RGB LED ULTRA LOW Deep Sleep Current USB-C Connector with back-feed protection USB ESD protection Native USB + USB Serial JTAG LiPo Battery Charging + PicoBlade connector NEW I2C Battery Fuel Gauge 5V Sense Pin NEW 3D High Gain Antenna AND u.FL connector STEMMA QT connector powered by LDO1 27x GPIO including castellated headers JTAG pins on the header NEW! Two antenna options on the one board! ProS3[D] now includes an onboard antenna and a u.FL connector for an external antenna on the same board, and you can switch which antenna to use via the RF switch on the fly from inside your code! The onboard antenna is selected by default, so you never need to worry about the RF switch being in a bad state, or the ESP32-S3 getting damaged if you forget to plug in an external antenna. 2x 3.3V Regulators? Really? Yup! The first one is for the general operation of the board and the ESP32-S3, PSRAM and Flash. The second LDO is for you to use to connect external 3V3 modules, sensors and peripherals, and it has programmable EN control tied to IO17 + it’s connected to the deep sleep capabilities of the ESP32-S3, so if the ESP32-S3 goes into deep sleep, the 2nd LDO is automatically shut down for you! LDO2 also powers the onboard RGB LED. Both regulators are ultra low noise and have ultra low quiescent current, and both support a maximum of 700mA output. Pinout Board Dimensions: 55mm x 17.8mm Max Thickness: 5.4mm at the vertical STEMMA QT connector Development Platforms Unexpected Maker ESP32-S3 boards ship with CircuitPython pre-installed!
