#f03c15 1/03/2023 - This device has a realtek chip. We will swap in ESP32-C3-12F Chip

Additional Hardware​

You'll need to buy yourself an

ESP-C3-12F Chip

ESP burner

Pre-Flash ESP-C3-12F​

Chip Flashing​

Our ESP Burner isn't designed for use with the ESP32-C3 in particular but because they are both the 12F format it will work. It will require for use to a few jumper wires. You can see which pins to apply here in this diagram:

We want to flash WLED onto the chip but because this is an ESP32 chip you need to flash the factory firmware image then use wled

Compile WLED​

To setup VSCode/Platformio to compile visit here

We need to comment out or delete this line in https://github.com/Aircoookie/WLED/blob/main/wled00/pin_manager.cpp#L246

Line to ommit because we need to use GPIO pin 18 and 19:

    if (gpio > 17 && gpio < 20) return false;     // 18-19 USB-JTAG

Here is a sample of the platformio_override.ini file used

[platformio]
default_envs = WLED_drchop_corner_lamp

[env:WLED_drchop_corner_lamp]
board = esp32-c3-devkitm-1
platform = ${common.platform_wled_default}
platform_packages = ${common.platform_packages}
framework = arduino
board_build.partitions = tools/WLED_ESP32_4MB_1MB_FS.csv
upload_speed = 460800
build_unflags = ${common.build_unflags}
lib_deps = ${esp32c3.lib_deps}

After you build/compile the code it'll show up in the directory build_output/release/WLED_VERSION_drchop_corner_lamp.bin

Pre-Compiled WLED​

WLED-0.14.0-b1 with GPIO pin 18 and 19 enabled

Use ESPtool to flash it to the memory spaces 0x0

Instructions here

esptool.py write_flash 0x0 wled-0.14.0-b1-esp32c3-4m-gpio1819enabled.factory.bin

Open it​

Pry the back open

Desolder un-needed components​

Add Leaded Solder​

Get some leaded solder and melt some on the existing pins of the Realtek chip

alt text

Heat em up! Pull em off! RAWHIDE!​

Now use your hot air tool, soldering iron, or heat gun to remove the chips

Solder new stuff​

Now we want to solder the new chip back on

ESP32 C3 12F​

Use some solder wick and clean up the pads where you pulled the Realtek chip from, this will allow the ESP32 C3 12F chip to sit flat on the PCB

Place the ESP32-C3-12F on the board and solder it into place alt text

Reassemble the board back into the case alt text
