README
README.mdArduino-Mega Compatible Secure Connectivity Development Platform
WARNING: This project is under development and has not yet been validated.
This is an open hardware platform designed for the development of secure wired-network applications. It is fully compatible with all Arduino Mega-compatible hardware and software.
This project was inspired by (but not a copy of) the Freetronics EtherMega: https://github.com/freetronics/EtherMega This project was created as an alternative to the platform offered by Freetronics.
Features:
- CH340 USB->Serial Converter (Functionally similar to FT232, Driver should be installed automatically)
- Jumper Configurable IO: Certain pins (D3, D6, D8, D9, D13) can be connected to the headers or to integrated peripheral pins.
- 5V 2A USB-C Input
- 6V - 32V VIN Input
- MicroSD Card Slot
- 10/100 Ethernet provided over SPI using the W6100. Supports Auto-Negotiations, IPv4, IPv6, and Auto-MIDX.
- SE050 EdgeLock Plug and Trust Secure Element to provide security features for connected applications, accessible using I2C
- ISM330DHCX Inertial Measurement Unit, accessible using I2C
- MCP7940N Real Time Clock, accessible using I2C
- Level Shifted I2C: Provides connection points for 3V3 I2C Devices (Extra Header), and 5V I2C Devices (Standard Mega Headers)

Questions
How big is the ArduinoMega Ethernet PCB?
It measures 101.6 × 53.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ArduinoMega Ethernet use?
116 parts, built around the ATMEGA2560-16AU, CH340C, AP63203WU and AP63205WU. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the ArduinoMega Ethernet KiCad files?
From the dmanla/SecureConnectivityDevelopmentPlatform repository on GitHub, at the commit this page was made from: the board is ArduinoMega_Ethernet/ArduinoMega_Ethernet.kicad_pcb and its schematic ArduinoMega_Ethernet/ArduinoMega_Ethernet.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ArduinoMega Ethernet design in my own project?
Its repository states no licence, so its author keeps all rights: ask dmanla before reusing the design.
