Good Value
Works as described. One LED was slightly dim but replaced it easily. Good for understanding interrupt handling.

Great Learning Tool
Bought this for my electronics club. The schematic is clear and the 8051 code examples are well commented. Soldering was straightforward.
Q: What is the maximum voltage?
A: Do not exceed 5.5V DC to avoid damaging the MCU.
Q: Can I add more channels?
A: Hardware is fixed at 8, but code can be modified for different logic.
Q: Can this run on battery power?
A: Yes, any 5V DC source works, including power banks.
Q: Is a programmer included?
A: No, you need a separate 8051 ISP programmer.
Q: Is the source code editable?
A: Yes, full C and Assembly source code is provided.
