GW-USB-13A
Hardware
GW-USB-13A is a generic equipment, i.e. the hardware is fixed and the user can implement specific functionality by
software only. Detailed information for designers is available in the DS-PAGER development set.
Power supply
GW-USB-13A is intended to be supplied via micro USB connector, either from PC or from the adapter. The
accumulator serves as a backup for external power source and should be charged from it.
Sleep mode
It is possible to switch off all functions and peripherals for current consumption minimizing, especially in idle or while
supplied from the accumulator. GW power is not switched off, the Sleep mode is used instead of this.
EEPROM memory
Capacity: 64 kb, serial interface SPI (shared with the TR module), 1 000 000 erase/write cycles (typ.).
Pushbuttons
Functionality of all three pushbuttons is fully under software control.
Beeper
The functionality is fully under software control.
TR module
The transceiver module is inserted in SIM card connector. User program should be uploaded by an external
programmer outside the GW or inside the GW using RFPGM wireless upload (RF PGM should be enabled in external
programmer first) – see the IQRF IDE help.
Antenna
PCB antenna built-in GW-USB-13A board.
Case
The plastic case is limited to a very few number of open/close cycles only.
Tip:
The TR module can be uploaded wirelessly via RFPGM with the case closed.
