This board allows you to develop easily an application with Ethernet connectivity. It has everything you would normally need for such a purpose: power relays which you can command through web interface. LCD display which will display messages you fill in web forms, analogue inputs for connection to sensors, digital optoisolated inputs, trimmer potentiometer, temperature sensor, Ethernet connector. With this board you can easily automate your home and then control and monitor it from any point in the world via Internet. The extension connector is available so you can connect your cusom made hardware hassle free. The PIC18F97J60 has 128KB Flash programming memory and there is also an external 1Mbit (128KB) flash memory for data storage. The on-board DC/DC converter makes this board very tolerant to the external power supply which could be in 9-25V DC or 7-18V AC range, the bridge rectifier on the input allows both AC and DC adapters usage and makes power supply polarity problems go away.

Documents Hardware Software
  • Example based on Microchip's stack v5.42 refer to the Olimex License Agreement.pdf and Read Me.txt inside
  • Microchip-5.31 stack free Microchip's TCP-IP stack tuned for PIC-MAXI-WEB with DHCP disabled and IP set to, all boards are shipped with pre-loaded TCP-IP stack
  • Production test binaries in zip format (the initial program the board was programmed with)
  • There is a known issue with C18 V3.37.01 & TCIP/IP V5.31 (or TCIP/IP V5.00). The fastest workaround is to use the previous C18 (v3.34) until the next C18 version is released. Another work around is to use this p18f97j60.h
