Review on Gikfun DIY Electronic Clock Kit: 6-Bit LED Digital Time Display for Arduino Projects - AT89C2051 FR-4 Soldering Learning Board (EK1323) by Jay Huang
Not for home automation beginners
Requires soldering of external power cables, USB power supply not included. Comes with no instructions other than the PCB instructions printed above. I built it, which took a few hours, and since I don't have an external power supply, the cable I created doesn't work too well. I can tell there is power because the beep is muted, but there is no activity on the displays. Bad buy!
- One year trial
- Not all will fit
