This circuit is a small “on-board” temperature recorder for RC models.
For those who practice this hobby know that the engine temperature is very important, not only for performance but also to ensure the smooth operation and durability of the engine.
It records the motor temperature of my helicopter in flight 2 times per second and stores it in memory.
The PCB size is only 51×30 centimeters.
Internally has a 16F88 microcontroller from Microchip that is the heart of the recorder and a 24LC512 eeprom memory also from Microchip divided into 4 blocks. This way I can make 4 independent data recordings, extract, delete and re-record individually.
Each memory block stores up to 15-minutes of data which for helicopter flights is more than enough.
