Variometre

Here the first Paragliding Computer I’ve designed :

This is a variometer / gps / sd logger Atmega328p based project :

Components :

• a SD card reader connected through SPI to the arduino
• a Nokia LCD screen connected to SPI
• a BMP180 (pressure sensor) connected through I2C
• a GPS Neo-6M receiver in UART.

The PCB is powerd by a 1s battery + a USB battery charger and a boost module to generate 5V.
