Its main chip is the 32F103C8T6, from the STM32 family. By type, the board carries 10 capacitors, 6 resistors, 2 connectors, 1 IC, 1 crystal and 1 diode.

It belongs with the retro computing designs in this gallery.

From the project

A board to perform upgrades to the Lava RSC Lite famiclone

Any use of this project is under your own responsibility. You will be responsible of checking the correct construction and functionality of your board. By using this project You will agree that I cannot be held responsible if it will destroy any of your devices, damage your computer, burn down your house or whatever.

I want to stress this out: You're on your own using this. It works for me, I cannot give guarantees to you. Also, do not go bother the Lava RSC people about it for support!!!
