Usbpicprog.org released a new version of the hardware design (v0.3) with some new features:
* New transistor circuit for VPP line which allows faster transition from 0 to 12V
* Possible to set VPP to 5V allowing it to run the target board and in the future for programming low voltage (3.3V) devices
* PGD and PGC can now switch to 3.3V level
The corresponding software version 0.3.0 is to be released soon!
