ESP32 One Mini Development Board

This compact development board utilises an ESP32 processor for a very low-power project foundation including WiFi, Bluetooth, MicroSD storage, an onboard microphone and the option of a 2MP camera (select version above before adding to cart)! With the added flexibility of direct LiPo powering and charging thanks to the dedicated JST (PH2.0) connector, this mini dev board is great for remote, low-power monitor projects where size and power consumption are key. Whilst this won't run a full operating system like the Raspberry Pi, the ESP One is compatible with Arduino libraries and can be programmed using popular options such as Microsoft Visual Studio Code. You can even use most of your existing Raspberry Pi HATs and pHATs with this board thanks to the standardised 40-pin connector format. Other great features include the colour-coded header, onboard reset button, IPEX antenna connector, LED indicators and more! Features (Optional) OV2640 camera - supports applications such as image recognition, voice processing etc Digital microphone onboard Standard 40-pin GPIO header - compatible with most Raspberry Pi HATs Integrated Li-ion battery boost charging manager - supports battery charging/discharging Board can also be powered via the Micro-USB connection Compatible with Arduino and ESP-IDF software SDK - seamlessly connecting with ESP-WHO applications Onboard 8MB PSRAM, 4MB FLASH storage Supports SD storage CP2102 USB to UART converter - for serial debugging/programming 4x LED indicators - easy to check the operating status Online development resources and manual Package Contents 1x ESP32 One main unit (with/without camera - select above) 1x USB-A to micro-B cable 1x Screws pack What's Onboard 1) ESP32-D0WDQ6-V3 processor 2) 40MHz passive crystal oscillator 3) Reset button 4) CP2102 USB to UART converter 5) Indicators PWR: power indicator LED: PWM control indicator DONE: Li-ion battery fully charged CHG: Li-ion battery charging 6) CS8501 Li-ion battery charge manager 7) 32.768KHz passive crystal oscillator 8) OV2640 camera (optional) 2MP (UXGA 1622×1200) 9) MSM261S4030H0R digital microphone Sensitivity -26dBFS @1kHz 1Pa 10) RT9166A-28PXL power chip 11) RT9193-33 power chip 12) RT9166A-12PXL power chip 13) ESP-PSRAM64H RAM 14) W25Q32JVSSIQ FLASH 15) Raspberry Pi GPIO header Compatible with Raspberry Pi HATs 16) Micro SD card slot 17) IPEX antenna connector 18) USB TO UART port 19) 4.2V Li-ion battery connector PH2.0 single cell 20) DVP camera interface Resources Product Wiki and user manual Pinout Specifications WiFi: 802.11b/g/n Bluetooth: Bluetooth 4.2, including traditional BR/EDR, and BLE low-energy Processor: Xtensa LX6 dual-core processor @240MHz Camera (optional - select above): OV2640 (UXGA 1622×1200) SRAM: 520KB+8MB Flash: 448KB+4MB Input Voltage: 3.3V~5V Operating Voltage: 3.3V Charge Current: 1A@5V Overall Consumption: 7.7mA@5V (ESP32 under deep sleep) Dimensions: 65mm × 30.5mm Operating Temperature: -40℃ ~ 85℃
