Arduino MEGA 2560 Rev3 shield build template
Template is drawn on Document layer for easier copy-pasting into existing layout designs. Enable this layer to see the drawing.
The template contains the following:
- Arduino PCB outline
- Location of high components (electrolytic capacitors, USB and power connectors)
- All header connectors
- All mounting holes

**Open Solar Energy Diverter**
This project have the aim to divert not comsumed electricity produced by photovoltaic panel to water heater to keep energy produced in the area of usage.
This project is base on idea from [http://energie-autrement.blogspot.com/p/plans-eolienne.html]...
RS232 to TTL adapter using MAX233 chip. Includes DTR support so that COM1 on PC can be used to program Arduino from IDE. Optional +- 10V output pins. The TTL output pin layout is similar to the popular FTDI USB TTL serial adapter apart from no CTS support. An external 5V source is required to power this circuit.
Interface a Raspberry Pi 3.5 inch TFT LCD to an STM32F103C8T6(blue pill). This LCD with resistive touch screen uses SPI to connect to the STM32. Can also be used to connect to Arduino Pro Mini by adjusting relevant SPI pins.
Connect 2.4Ghz Nordic NRF24L01+ transceiver to Arduino and run the pingpair_ack example sketch from the RF24 library. A pair of these will communicate over a range of approx 10-20m indoors with 2 concrete walls in-between. Range outdoors is approx 20-40m. The scanner sketch is also useful to find free channel in heavy wifi traffic.
## 360° Rotary encoder for arduino ##
360° Rotary encoder (rotary encoder) can be converted into a rotational position or rotation amount signal (analog or digital), through a certain way (mechanical, optical, magnetic, etc.), that the axis of rotation, and send a signal to inform us. Can be divided into absolute type (absolute) and incremental (incremental) or called a relative type (relativ...
PoE (Power over Ethernet) to USB 5V adapter.
Current use cases:
- Power micro controllers (Arduino's or Pbpi's)
PoE Switch --> **PoE to USB** --power--> Rbpi
Switch ------------Data----------------> Rbpi (There is still a second Ethernet cable needed for data over cable.)
- Charge your Phone or other USB devices
- Trying to support 802.3af
