 You can replace with your own ROM, using srec_cat to generate the C Array. See my [ROM Software repo](https://github.com/olivierjan/ROM-software-for-6502-SBC) for more details. 
 
 The code is very basic but is meant to help debug a hombrew computer. It can be greatly optimised and I will try to add new features over time (usable debugging, support for VIAs and other components, etc...).
 
-**WARNING:** Teensy 3.6 is only 3.3v and will provide power to the whole circuit. A 5V version should be possible using Teensy 3.5 but I haven't tested yet.

+### PCB Board
+A PCB to host the Teensy and the 65C02 is provided, I designed it using EasyEDA and ordered it from JLCPCB.
+I provided the design here in Altium and Gerber format, but haven't tested these, only the EasyEDA.

+The PCB can be plugged in an existing circuit, and you can choose to power the circuit from Teensy or not using the jumper.
