Could be a good product if it's support existed.
For OSHChip CMSIS-DAP V1.0 SWD Programmer and more
The web site contains a series of pages whose only content is "Not yet written". In contrast to other microprocessor boards, OSHChip has no boards support for the Arduino IDE and no examples appear to have been published. At this stage, it is a waste of $100 to have bought 2 OSHChips and a programmer. At $25 each, these chips could be worth purchasing only if they were well supported. They are not.
