Compact Adapt11-style module with a standard 9-pin serial connector, and socket for user-supplied MCU. On-board 5V regulator. It is commonly used to read and program one-time programmable (OTP) chips (ie. 68HC711E9 and 68HC711E20). A guide for doing this can be found here.
This board supports "burning" OTP 68HC711E9 and 68HC711E20 chips! You supply Vpp (regulated 12VDC). Production programmers for 68HC711 chips are well over $1,000 these days-- if you can find them-- so this product makes a very attractive low-cost solution (less than $100) for occasional use!
It can also be used with BUFFALO (i.e. 68HC11E9 chip) as a trainer, or embedded into your design with your own 68HC711 chip. All I/O lines are brought out to a standard 50-pin (2x25) connector footprint, on a 0.1" grid. Several connector styles are offered. Choose the "SB" connector option if you'd like to plug this module into your solderless breadboard vertically, with the footprint of a DIP chip. Or choose the "RA" connector option if you plan to use it with a ribbon cable. (If you're just going to use it as a chip programmer, you don't need a connector, so choose the NC connector option for H1.)
