Sparrow On-Board Unit

The “Sparrow” is one component of RC Electronics model aircraft telemetry system. The Sparrow is the “on-board” unit intended to be used with the “Snipe / Finch” “Ground station” or with Jeti back-channel link.  The Sparrow is designed to measure many parameters of an R/C model aircraft and transmit them to the  ground via the telemetry channel working on 433 MHz frequency (Sparrof RF module needed) or Jeti ExBus. The unit is capable of measuring sink/climb rate (Vario), altitude, noise level, servo pulse on servo inputs, GPS data with 5Hz refresh rate and supply voltage. For storage it has external 8Gb SD card.
