This is a lower cost alternative to the Atmel ATDH1150USB programmer for the ATF15xx family of CPLD's. It's based on the same FTD2232D USB transceiver and SN74LVC1T45DBV level convertors for the JTAG signal lines so it works with 5V, 3.3V, 2.5V and 1.8V devices and is recognized as a ATDH1150USB by Atmel's ATMISP software.

It connects via USB-C to your host computer and via a standard 2x5p 2.54mm JTAG port to your target device.

Before designing this I struggled with trying to program some ATF1504AS and ATF1508AS CPLD's in a two device JTAG chain with generic FTDI based programmers and software like OpenOCD. While the official programmer worked great doing the same, the high price of almost $100 these days motivated me to create a lower priced option for the DIY hobbyist.

Package includes an assembled and tested PCB inside a 3D printed case.
