r. Velleman K8055N board to 32-bit PIC32MX250F128B/PIC32MX270F256B and 16-bit PIC24FJ64GB002 adapter schematic

32-bit PIC32MX250F128B microcontroller is much more powerful than an 8-bit PIC18F2xJ50. It enables a wide range of new programming options. Here is the adapter that makes your K8055N experiment board (for K8055 experiment board upgrade and to see photos click here) 32-bit and also adds an optional PICkit 2 and 3 programming/debugging connector:

VB.NET application for PIC32MX250F128B is available in PIC32MX250F128B_Example 1.zip or PIC32MX250F128B_Example 1 (x64).zip file from Downloads section.

VB.NET application for PIC24FJ64GB002 is available in PIC24FJ64GB002_VB Example 1.zip file from Downloads section.

a.) Simplified version that enables use of the original K8055N board programming header with PICkit2 or PICkit 3, but relays must be rearranged according to the new layout. See the schematic bellow for details:

b.) Version with optional programming header that preservers relay outputs arrangement:
