Description
Power Supply. +5.0V @ 1.3 A
Power Supply Ground Return
No Connect
Active High Power Enable. Grounding this pin shuts off entire module. Minimum logic
high voltage is +2.5V. 5V tolerant. Low impedance driver or a pull up resistor less than
2K required.
3.3V CMOS logic-level UART transmit pin
5V tolerant CMOS logic-level UART receive pin
5V tolerant Active Low Reset Pin. 10K internal pull up, interface with open collector
driver. When held low, WJM draws current but will not respond to commands. If nBL/
nPD is held low as nRESET is brought high, the WJM enters Bootloader mode. If nBL/
nPD is held high as nRESET is brought high, the WJM application starts. This pin can
be left unconnected for minimal hardware configuration. A reset controller may be re-
quired if power supply rise time is slow.
5V tolerant Active Low Bootloader/PowerDown pin. 10K internal pull up, interface with
open collector driver. This pin serves two functions.
This pin can be left unconnected for minimal hardware configuration.
3.3V logic-level 3-state output:
Logic high: OK
Tri-State: Sleep Mode
Logic low: Error
Currently FW configures these pins as outputs, they display various debug and status
signals to LEDs. If unused they can be left un-connected.
