JESSINIE 2Pcs C8051F300 MCU Single Chip Microcontroller Development Board Mixed Signal ISPFLASH Microcomputer Module Board CJMCU-8051 Industrial Control Module

I worked with the 8051 single chip micro-controller for years back when I was an embedded engineer, so I was really excited to see the JESSINIE 2Pcs C8051F300 MCU Single Chip Microcontroller Development Board come across my data feed. At last, a chance to relive my misspent youth on a complete development system! Unfortunately, unless the definition of a Microcontroller Development Board has changed in the years since I was heavily involved with embedded systems, this is not it.I expect a development board to be complete and self contained. This board is simply the circuit board and a couple of header pin assemblies. This is not a 'plug this cable into PC and run this IDE' type of environment.Okay, let's say that I'm too demanding (or too lazy), and I really should expect to solder the headers and wire in a connection to the PC. How do I do this? There are no instructions. There is a plethora of information available in the Internet regarding the Silcon Labs chip on which this board is based, but nothing from JESSINE. You are completely on your own to use this board.In my opinion, this is not really a development board. It is an OEM circuit board that you can use in your own projects, but you better know what you're doing. I have enough technical knowledge to be able to work with this board, but I suspect the normal developer does not. Unless you see this board and know immediately how to work with it, this board is not recommended.

Good board, cheap. Packaging and handling from this supplier is bad. Both boards' bags were damaged from crush force, and one board was damaged.
