Interesting Bits and Pieces

WiFiG25

http://armdevs.com/WiFiG25.html Atmel G25-based small board, like the Arietta G25, but with an USB WiFi module already integrated, and with 256MB flash onboard

PL9823 Programmable RGB LEDs

Everybody loves the WS2812B, but sometimes, you need a classic 5mm LED. Adafruit's NeoPixel apparently is a PL9823 (datasheet), availablable at some AliExpress stores and at LED Genial. Also Soldering Sunday, Cool Components.

Burning Firmware

There seems to be little consolidated information, so here's my experiences so far.

{{#if: The bootloader is not protected; overwriting the bootloader with a non-functioning version will brick the module. |

The bootloader is not protected; overwriting the bootloader with a non-functioning version will brick the module.

| Note Note: }}

The ElectroDragon firmware for the Wi07c mode can be programmed like this:

$ esptool.py --port /dev/cu.usbserial write_flash 0x00000 Electrodragon-V0925/eagle.app.v6.flash.bin
$ esptool.py --port /dev/cu.usbserial write_flash 0x40000 Electrodragon-V0925/eagle.app.v6.irom0text.bin

Note that the command given on their page lists the load address for the irom0 part as 0x4000 which is wrong, it must be 0x40000.
