NOTES:
N/A – not applicable
VIO – I/O logic level. VIO is 2.8V by default; can be configured to 3.3V by
changing 0 ohm jumpers on the board.
1. SUPPLY pins are internally connected.
2. Disable input for WiFi supply (independent of GPS supply). Pin is
internally pulled up to SUPPLY voltage and can be left floating for always-
on operation. For shutdown, pull low with open collector/drain driver.
3. The GS1500M UART interfaces are cross connected to appear as a
DCE devices on the WiFi1500CF pinout.
4. N/C (no connection). The pin has no function and makes no electrical
connection.
5. Must be enabled by installing 0 ohm jumpers on the board. See
Configuration Options section.
6. Not supported in standard firmware
7. Enable input for loading GS1500 firmware. Pin is internally pulled up
to VIO voltage and can be left floating. For enabling firmware load,
pull low with open collector/drain driver. (There is also provision for a
jumper for this on the board.).
8. Connected to GS1500 RESET pin and a 22K pullup resistor to 3.3 V
through a 1 k series resistor.
9. Only available on WiFi1500CF V1.0 boards (with GPS). Pin is N/C
(no connection) on WIFi1500CF V2.0 boards.
