The features of this module are as follows:

This module is the replacement for the original ProgRock kit. It is much smaller than the original ProgRock and ready-assembled. It does not have ProgRock's 4-way DIP switch for programming (which was a bit awkward anyway); there is a micro-USB connector for programming via a PC serial terminal and for firmware updates.

Several ways to install the ProgRock2 module in your projects:

1) You can choose the pin headers option at checkout. The board fits in between the rows of headers. So it can be plugged in to a 2x6 pin female socket on a motherboard. The board was carefully designed such that the three BAND select, 3 clock outputs, and power rails are all accessible along one edge.

2) Another option at checkout is the right-angled 2x6-pin headers; these can be installed also by sliding the PCB edge between the pins as shown; then the full 24 connections are available. That could be soldered into a position on your board, or plug into female pin header connectors, for example.

Yet another way is to install the ProgRock2 module inside its very own enclosure, an HC6 crystal case! The ProgRock2 module was specially designed such that the pads at the board end are Gnd, V+ and CLK 0. One of the HC6 crystal holder pins can be soldered to V+, the other to CLK 0, and the ground connection made to the enclosure.

Finally, what about old-school PCB edge-connectors... this picture shows the little test and bootloader flashing jig in use at QRP Labs HQ for preparing all ProgRock2 boards. The 0.1-inch pads line up nicely with the edge connector sprung contacts. This particular one is many decades old.
