Re you suggesting that a Development Board has the wrong regulator?? Erik Yes Erik, It is my opinion that the wrong regulator is used on that development board. Reasons: 1. The data I have for the AT89C5131 micro shows it as a 3V device. 2. The PCB overlay shows a 3V testpoint. 3. The regulator used is an LM7805. Tony [Adelaide, South Australia] |
