Synapse SS200
Synapse also offers the SNAP Stick 200. This device, based on the ATMEL ATmega128RFA1
hardware, is a USB dongle - about the size of a thumb drive. It is designed to act as a bridge between
Portal or SNAP Connect and your 802.15.4 2.4 GHz wireless network.
Because it is based on the ATmega128RFA1, the SS200 has the same capabilities as the underlying
hardware, relating to sleep options and radio rates.
The USB dongle form factor means that only
one UART is available on the SS200. UART1
connects through the USB port. If you change
the default UART (NV Parameter 12) to 0, you
will not be able to communicate directly with
the device, and will have to either use Portal to
Factory Default NV Params or use a different
SNAP Device as a bridge and reset the default
UART over the air.
Also because of the form factor, you do not have normal access to the GPIO pins on the SS200. The
device was designed to primarily act as a bridge device. The only feedback available from the device
comes in the form of a tri-color LED, controlled by pins 5 and 6:
LED State Pin 5 Pin 6
Off
High (True) High (True)
Red
Low (False) High (True)
Green
High (True) Low (False)
Amber
Low (False) Low (False)
The SS200 includes an internal power amplifier. It also has a 32 kHz crystal, so for most efficient
sleep you should use sleep mode 1. Note that there is no way to trigger an external wakeup signal to
the device, so you should be careful to only use timed sleep.
