WiFi-Gate-Controller
About the WiFi-Gate-Controller PCB
WiFi-Gate-Controller is an open source Microchip SAM PCB design by mikelawrence, published on GitHub under the MIT license. It is a 2-layer board measuring 66 × 51.5 mm, with 86 components from 38 distinct parts.
Its main chip is the ATSAMD21G18A-MUT, from the Microchip SAM family. Other key parts include the BTS3800SL, LMZ21700SILR, DS18B20U+, SN74LVC2G14DBVG4 and ATWINC1500-MR210UB1140. By type, the board carries 26 resistors, 20 capacitors, 17 diodes, 12 ICs, 5 inductors and 3 connectors.
It belongs with the iot & wireless and power & battery designs in this gallery.
From the project
WiFi enabled Gate Controller Addon to US Automatic Gate Opener
This board is designed for and tested with a US Automation Gate Opener.
This PCB design uses my custom libraries available here Mike's KiCad Libraries.
Note: The LMZ21700 Simple Switcher, SAMD21G18 ARM Processor, and ATWINC1500 WiFi Module have exposed pads on the bottom which requires either a reflow oven or hot air to solder properly.
For Bill of Materials generation I use my version of KiBoM forked from SchrodingersGat.

WiFi-Gate-Controller: common questions
What microcontroller does the WiFi-Gate-Controller use?
The WiFi-Gate-Controller is built around the ATSAMD21G18A-MUT, from the Microchip SAM family.
How big is the WiFi-Gate-Controller PCB?
The WiFi-Gate-Controller measures 66 × 51.5 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the WiFi-Gate-Controller?
86 components, from 38 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the WiFi-Gate-Controller design files?
From the mikelawrence/WiFi-Gate-Controller repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the WiFi-Gate-Controller design in my own project?
Yes, under the terms of its MIT license, which mikelawrence chose for the repository.
Can I test firmware for the WiFi-Gate-Controller without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Microchip SAM firmware against it before you order a PCB.
