Kit #1 – “PropCade 128”
PropCade PCB, *COMPLETE* kit with 128KB SRAM for $109+s/h
Complete means complete – the only empty sockets on the board will be two of the 8 pin dip memory expansion sockets – please see the feature list at the top for what is included.

Kit #2 – “PropCade Essentials”
PropCade Essentials kit for $39 + s/h
Since a lot of Propeller enthusiasts will already have most of the parts needed to populate PropCade, I thought it would be useful to make a “Bare Kit” consisting only of the parts that are not readily available from DigiKey.
This kit includes ONLY the following parts:
- PropCade printed circuit board
- 6.25Mhz crystal
- uSD socket
- power switch
- triple RCA socket that PropCade is designed to accept
- two of the RJ45 unshielded connectors I use
You will have to supply all of the other parts.
