This is a PIC-BASIC board that was previously sold at Akizuki Electronics. It cannot be used as is. You will need the PIC-BASIC development software (117839) from Akizuki Electronics. It seems that Akizuki Electronics still sells a usage guide as well. - Model: PIC16F877 - Size: 40-pin DIP - Operating Frequency: 20MHz - Accessories: Pin headers - Version: PIC-BASIC version 1.0 This item has been stored for a long time. It was kept as a spare. It should be unused, but please erase any data if it has been written to. It was an easy-to-use BASIC for simple processing. Thank you for looking.
