Versaloon can program hardware from several manufacturers

Versaloon is an open source, USB connected project, that centers around an STM32 processor and provides a standard JTAG pinout. Above you see the Nano version which has a 10-pin JTAG connector, but there is also a 20-pin option on the Handy model. Great, another JTAG programmer. Well this can do a bit more than that. With a bit of help from the software it has been turned into a programmer for ten different types of hardware. Obviously this should be able to program anything that works with the JTAG protocol, but the script adapts it to work as an In System (or In Circuit) Programmer too. So far the list of programming targets includes STM32, LPC1000, LPC900, STM8, AR8, MSP430, and a few others.

We had some trouble finding an actual picture of this hardware. If you’ve got one, snap a picture and leave a link to it in the comments along with your thoughts on the device.

  1. It doesn’t seem to have any level conversion/buffering except for some in-series resistors between the JTAG port and the MCU.. how does it handle targets of different voltages?

    If you just want to play with ARM targets get a J-Link clone off of ebay or get one of the FTDI based dongles (however much people say these are cheap, I’ve never seen one “cheap”, not in comparison to a j-link clone anyhoo) and use it with OpenOCD. I think OpenOCD can be used with some Atmel targets now too?

    Major cell phone manufacturers have agreed to use a standardized power supply adapter. Why this solution is not used in other electronic fields? I have many JTAG adapters and still there are boards that need dedicated JTAG interface.
