INTRODUCTION:
MOD-WiFi module gives you the opportunity to add WIFI to any of our
development boards with UEXT connector. There is ready made support in
Microchip's TCP-IP stack so you can use MOD-WIFI with any PIC board with UEXT
and you have hands on the complete source code.
BOARD FEATURES:
– MOD-WIFI extends OLIMEX boards (that have a UEXT connector) to have Wireless
internet access
– Uses Microchip MRF24WB0MA module
– Works with Microchip TCP-IP stack
– PCB: FR-4, 1.5 mm (0,062"), soldermask, white silkscreen component print
– Dimensions: (29.00x22.50)mm (1.14x0.86)"
