Now and again we see our products "out in the wild", and another example has been reviewed by a popular video blogger MrHobbyelectronics - who demonstrates how easy it is to upload the LUA firmware to an ESP8266 ESP-01 board using our USB Serial adaptor.
By using LUA with the ESP8266 you can have a much easier development experience, thanks to the ease of programming in LUA vs. dealing with the standard AT command set and a separate mircontroller to harness the power of the ESP8266. His tutorial explains how to connect the USB to serial adaptor and flash the new firmware to the module - as shown in the following video:
If you're experimenting with serial ESP8266 modules - or using other circuits that need a serial to USB interface, check out our USBserial module:
It offers much more than the typical FTDI-based adapter. Apart from dual-voltage USB-serial support, it's also a full ATmega16U2 breakout board with all I/O pins arranged for easy access. The board can be flashed easily, and has the pinouts for a USBasp programmer. For more information including our Quickstart guide and of course to order - visit the USB Serial product page.
