One of the earliest 32-bit hobby kits!|
Licensed under CERN OHL v.1.1!
Based on PIC32MX110 in DIP package.
MIPS instruction set (using C language).
May work on 80 MHz.*
Internal or external crystal.
All I/O are 5V-tolerant.
Programmable by PICKit2 or PICKit3.
Sample source code: nedo32t1.c
* 40 MHz is recommended for DIP packages.
