OpenTracker1+ SMT (OT1+ SMT) - Assembled and tested OpenTracker+ surface-mount (SMT) board. This version of the OT1+ is perfect for installation inside a radio or any other application where size and weight are a concern. Without pins installed, the board measures 1.22 x 0.72 x 0.2" (31 x 18 x 5 mm).
All off-board connections are through a double row of holes, in a standard 24-pin DIP footprint. Two pin header strips are provided (not installed) to allow the board to be mated with another PCB or installed in a solderless breadboard.
This board does not include a built-in temperature sensor or LEDs.
[edit] Pinout
Pin - Name - Function
- 5VIN Regulated 5-volt input
- RXD RS-232 data in (from GPS or computer)
- 1WIRE Dallas 1-wire bus for external sensors
- AOUT Audio out to radio
- ADC5 Analog input
- T1CH1 Timer channel
- ADC6 Analog input
- RST Reset (active low)
- ADC7 Analog input
- IRQ Transmit-now, profile select, or counter
- ADC8 Analog input
- ADC9 Analog input
- AIN Audio input from radio
- ADC4 Analog input
- ADC3 Analog input
- TXD RS-232 data out
- RED Red LED output
- GREEN Green LED output
- ADC2 Analog input
- ADC1 Analog input
- PTT Push-to-talk signal to radio
- REGOUT Regulator output - 5 volts
- GND Ground
- REGIN Regulator input - 6.5 to 28 volts
There is no on-board connection between the regulator output and the 5 volt supply. This allows the regulator section to be bypassed if an external 5 volt source is available. To use the regulator, either connect the REGOUT and 5VIN pins externally or place a small blob of solder on the two jumper pads on the bottom of the PCB.
When the telemetry option is enabled, the device will transmit an APRS telemetry packet containing 8-bit analog values for inputs ADC1-5 and digital values for inputs T1CH1 and ADC6-9
