OLIMEX© 2012 PIC-IO User's Manual PIC-IO development board User's Manual Rev.
OLIMEX© 2012 PIC-IO User's Manual INTRODUCTION: PIC-IO board was designed as simple platform which to allow control of appliances and devices with PIC, the idea was to build something like tiny PLC controller which is possible to program in C or assembler instead of the weird PLC relay language. Let’s see what we have on board: Four High voltage/ High Current relays – with NO-NC-COM contacts available on terminal block. The relay switching current is rated: 15A/125VAC, 10A/250VAC, 15A/24VDC.
OLIMEX© 2012 PIC-IO User's Manual have real RS232 driver (like PC) if you try to connect two PIC-IO boards by RS232 the connection will fail as no one of the boards will generate the negative levels. The on-board ICSP connector allow you to program the PIC on the board without pulling it of the socket, by ICSP programmer like PIC-MCP, PIC-MCP-USB, PIC-PG1, PIC-PG2, PICPG3, PIC-PG4 or to program and debug it with PIC-ICD2, PIC-ICD2-POCKET or PICICD2-TINY.
