From the project
This is a set of PCBs to test, in principle, X-HEEP chips (CHEEPs)... but, you can use it to test any chip you want, for what it matters.
This is a set of PCBs to test, in principle, X-HEEP chips (CHEEPs)... but, you can use it to test any chip you want, for what it matters.
The general idea is to recycle efforts, so all the things that are common to any CHEEP were moved into a main board. This one includes an FTDI through which you can program or communicate with your cheep, as well as some peripherals like flash, buttons, LEDs, etc. The main board also generates all the voltages needed by these blocks.
