Looks cheap compared to Viking lander.
The used a Guidance, Control and Sequencing Computer (GCSC) consisting of two Honeywell HDC 402 24-bit computers with 18K of plated-wire memory.
) uses a Qualcomm Snapdragon 801 processor with a Linux operating system. Among other functions, this processor controls the visual navigation algorithm via a velocity estimate derived from features tracked with a camera. The Qualcomm processor is connected to two flight-control microcontroller units (MCUs) to perform the necessary flight-control functions. It also carries an IMU and a Garmin LIDAR Lite v3 laser altimeter. Communications with the rover are through a radio link using low-power Zigbee communication protocols, implemented via 900 MHz SiFlex 02 chipsets mounted in both the rover and helicopter. The communication system is designed to relay data at 250 kbit/s over distances of up to 1,000 m (3,300 ft)
