What has a STEMMA QT connector for I2C devices, and a Lipoly charger circuit? What has your favorite Espressif WiFi microcontroller and lots of memory for your next IoT project?\u003cbr data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003eThat's right - its the new Adafruit Metro ESP32-S2! With native USB and a load of PSRAM this board is perfect for use with CircuitPython or Arduino, to add low-cost WiFi while keeping shield-compatibility.\u003cbr data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003eThe ESP32-S2 is a highly-integrated, low-power, 2.4 GHz Wi-Fi System-on-Chip (SoC) solution that now has built-in native USB as well as some other interesting new technologies like Time of Flight distance measurements. With its state-of-the-art power and RF performance, this SoC is an ideal choice for a wide variety of application scenarios relating to the Internet of Things (IoT), wearable electronics, and smart homes.\u003cbr data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003e\u003cstrong\u003ePlease note\u003c\/strong\u003e the Metro ESP32-S2 has a single-core 240 MHz chip so it won't be as fast as ESP32's with dual-core. Also, there is no Bluetooth support. However, we are super excited about the ESP32-S2's native USB which unlocks a lot of capabilities for advanced interfacing! This WROVER module we are using on the Metro comes with 4 MB flash and 2 MB PSRAM.\u003c\/p\u003e\n\u003ch3\u003eRevision History\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAs of 10th November, 2023\u003c\/strong\u003e - We added a right-angle Boot0 button so it's easier to press. We also changed the battery monitor chip from using a resistor divider (which worked OK but did not have great voltage precision) to the MAX17048 dedicated LiPoly monitor.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eESP32-S2 240MHz Tensilica processor - the next generation of ESP32, now with native USB so it can act like a keyboard\/mouse, MIDI device, disk drive, etc!\u003c\/li\u003e\n\u003cli\u003eWROVER module has FCC\/CE certification and comes with 4 MByte of Flash and 2 MByte of PSRAM - you can have huge data buffers\u003c\/li\u003e\n\u003cli\u003eLotsa power options - 6-12VDC barrel jack or USB type C or Lipoly battery\u003c\/li\u003e\n\u003cli\u003eBuilt-in battery charging when powered over DC or USB\u003c\/li\u003e\n\u003cli\u003ePrecision battery monitoring via MAX17048 on I2C\u003cbr\u003eUNO-shape so shields can plug in\u003c\/li\u003e\n\u003cli\u003eReset and DFU (BOOT0) buttons to get into the ROM bootloader (which is a USB serial port so you don't need a separate cable!)\u003c\/li\u003e\n\u003cli\u003eSerial debug pins (optional, for checking the hardware serial debug console)\u003c\/li\u003e\n\u003cli\u003eJTAG pads for advanced debugging access.\u003c\/li\u003e\n\u003cli\u003eOn\/Off switch\u003c\/li\u003e\n\u003cli\u003eSTEMMA QT connector for I2C devices\u003c\/li\u003e\n\u003cli\u003eOn\/Charge\/User LEDs + status NeoPixel\u003c\/li\u003e\n\u003cli\u003eWorks with Arduino or CircuitPython\u003c\/li\u003e\n\u003cli\u003e53.2mm x 72mm\u003c\/li\u003e\n\u003cli\u003eHeight (w\/ barrel jack): 14.8mm\u003c\/li\u003e\n\u003cli\u003eWeight: 22.5g\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eResources\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eProduct Overview\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Adafruit","offers":[{"title":"Default Title","offer_id":43493249024077,"sku":"nji1787258107734","price":17.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0644\/1182\/8301\/files\/adafruit-metro-esp32-s2_1.jpg?v=1787258112","url":"https:\/\/www.grandorchard.shop\/products\/adafruit-metro-esp32-s2","provider":"My Store","version":"1.0","type":"link"}
