TinyFPGA Programmer

by TinyFPGA

A convenient and inexpensive USB JTAG programmer for TinyFPGA A1 and A2 boards.

One of the goals of the TinyFPGA boards is to make FPGAs cheaper to use. The TinyFPGA A1 and TinyFPGA A2 boards aresp the first TinyFPGA boards and are designed to be the least expensive. As such, they do not include a built-in USB interface as that would increase the cost and complexity too much. Instead they rely on JTAG programmers.

Here comes the TinyFPGA Programmer. Rather than an FTDI2232 USB interface chip it uses a PIC16F1455 USB microcontroller. While not compatible with the FTDI2232 chip, the PIC micro has a much lower BOM cost allowing the programmer hardware to be cheaper.

The TinyFPGA Programmer slots onto the JTAG pins of the A-series FPGA boards. Using the TinyFPGA Programmer Application you can program .jed files generated by Lattice Diamond.

For more information on how to use the TinyFPGA Programmer with the A-series boards, see the A-Series Userguide at TinyFPGA.com

Works a treat. I'm now using old lithium batteries I scavenged from a vacuum cleaner to power my raspberry pi 4, save in the knowledge that the shim will keep my pi safe!

A great lightweight solution to put my Raspberry PI zero into a rocket and get some great photos from above.

The perfect power source for your Raspberry Pi Zero W HQ Camera combo! https://github.com/PaulZC/Pi_Zero_HQ_Camera_Adapter

It is a practically necessary piece of kit all things considered. I strongly recomment using it coupled with the stacking headers, so that you can still take advantage of the pins which aren't used by the shim

Great product as always! Wanted to add a lightweight power source to my raspberry pi zero robot and using this circuit with a LiPo battery was just what I was looking for.

This is a great piece of kit - you can either solder the board directly to the Pi's GPIO (like I did) or attach female headers that you can pop onto the Pi's headers if you want to remove it later on. I've also soldered a switch to the board, so that I can turn it on and off... well, at a flick of a switch! This makes a battery powered, yet compact, Raspberry Pi!
