{"product_id":"espflash-esp32-programmer","title":"ESPFlash ESP32 Programmer","description":"\u003cp\u003e\u003cstrong\u003eESPFlash programmer\u003c\/strong\u003e is designed for simple programming of boards based on \u003cstrong\u003eESP32\u003c\/strong\u003e and \u003cstrong\u003eESP8266\u003c\/strong\u003e microcontrollers. It's used to flash firmware onto boards that lack a built-in \u003cstrong\u003eUSB-to-serial\u003c\/strong\u003e converter, whether during development or when programming boards before they ship. It includes all the electronics and logic needed to flash firmware by plugging a \u003cstrong\u003eUSB-C\u003c\/strong\u003e cable into the programmer and connecting it to the programming header. On-board circuitry handles the timing and signal sequence to put the ESP microcontroller into bootloader mode automatically.\u003c\/p\u003e\n\n\u003cp\u003eThe board has a 6-pin header with GPIO0, RESET, RX, TX, 3V3, and GND. It uses the \u003cstrong\u003eCH340\u003c\/strong\u003e USB-to-UART chip and connects via USB-C. We have made this board open-source, so all hardware design files are available for you to inspect or adapt. Our technical support is also there if you need help getting started.\u003c\/p\u003e\n\n\u003cp\u003eIt works with the \u003cstrong\u003eArduino IDE\u003c\/strong\u003e and with MicroPython firmware uploads via esptool, along with other standard ESP flashing tools. Installing the CH340 driver is all the setup required on the software side. Two mounting holes for M3 screws allow for secure installation, and at 38 x 22 mm it takes up minimal space in any build. Full setup and usage instructions are available in the Soldered documentation.\u003c\/p\u003e","brand":"Soldered Electronics","offers":[{"title":"Default Title","offer_id":65122309669213,"sku":"333398","price":4.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0990\/5029\/1549\/files\/izo_w_e4cf99ca-e0ba-45c2-b1c1-f195149d6de6.png?v=1783065780","url":"https:\/\/soldered.com\/products\/espflash-esp32-programmer","provider":"Soldered Electronics","version":"1.0","type":"link"}
