This is a modified version of iSpindel drawer proposed in PCB format instead of 3d print. The project is available at: https://github.com/universam1/iSpindel Two folder for different pcb solution (short and long pcb)
PCB for PETlng 122mm / d33mm for iSpindel project (electronic Hydrometer)
- 1 Plastic cylinder (http://www.geoshop.lt/index.php?route=product/product&path=20_26&product_id=285#.WoBTg-jOXIU)
- 1 resistor 4k7ohm
- 1 resistor 220kohm
- 1 diode BAT43
- 1 Wemos D1 mini v3
- 1 Gy-521 Gyro & Acceleration Sensor (MPU-6050
- 1 Temperature Sensor (DS18B20)
- 1 TP4056 Lipo Charger micro USB 4 pin (mini USB is bigger)
