Versaloon – multifunctional USB platform

This might be great tool for makers and hackers. This STM32F203 based board is using a generic USB_TO_XXX protocol and is able to provide over 10 useful interfaces like JTAG, SWD, SPI, IIC. Despite various direct protocols it also gives more advanced functionality like timing control, pooling, nesting and other high level functions. This is a great starting point for various devices like logic analyzers, probes, scopes, programmers – and even more with additional circuits. Project is open-source and is available in KiCAD format.

Modified USBprog adapter becomes UsbProg-SHARP programmer

If you are looking for convenient USB based programmer adapter that can support multiple standards of programming you should go for a USBprog. This is great project and and even better that it is open source. Adapter is based on really cool idea. It flashes firmware from online pool on demand. You just have to select in special program what you will be programming and adapter updates itself by downloading firmware form server. Currently firmware pool includes following hex codes that converts adapter to: AVR ISP 2 clone; OpenOCD Interface (ARM Debugging); AT89 Programmer; SimplePort (10 I/O lines); USB to RS232 converter (without drivers!!); JTAGICE mk2 clone (under development). Site provides all schematics and PCB files for everyone to download and build adapters at home. But before you build one check this out. Dean Hall has modified this adapter with some small hardware changes that you may find interesting. He made following chages: Changed CONN1 to a type Mini-B receptacle (so it would be surface mount); Changed most parts to have surface mount packages (except jumpers and headers); Added capacitors… Continue reading
