bookmark_borderSHT20 Breakout board

About

This breakout board is based on the SHT20 temperature and humidity sensor from Sensirion. The sensor is pretty small and it can give decent results. The breakout board is only 10×10 mm making it ideal for projects that are compact. If you’re wondering if you can use this in an Arduino project you’ll be pleased to know that you can but however you’ll need to use a microcontroller that runs on 3-3.3V and that supports I2C. DFRobot has provided a very convenient Arduino library that you can use https://github.com/DFRobot/DFRobot_SHT20.Ā  The board is open source and you can find the github repo of this board at the end of the post

bookmark_borderCH340C USB TO UART BRIDGE

About this project

This simple USB to UART bridge is based off the popular and pretty common CH340C usb to serial chip. It also has an independent +3.3V regulator at the bottom of the PCB and has a type C port. Every single pin of the ch340c IC has been expanded in order to make full use of it or to possibly reconfigure it.

bookmark_borderStormduino is now OSHW certified !

A while back a project known as stormduino was started in collaboration with tecknologg and the cool folks over at cyberstorm.mu . Stormduino is pretty much a KiCad designed Arduino Uno compatible clone that utilizes a USB Type-c port and has much simpler components that still maintains it’s integrity. It was originally open source since Rev 1 but after refining the design, we wanted to really show that this was actually open-source hardware. After hearing about the open-source hardware certification program we decided to apply for it. To our luck, we got approved and celebrated with a cup of coffee šŸ™‚

bookmark_borderBerfboard 2.0 PSupply, a breadboard like protoboard with a power supply – Part 1

Berfboard was originally a prototype board that had designed to have connections similar to a breadboard but then I had an idea of combining a power supply into it. The power supply can provide +5V or +3.3V which would be ideal for certain Arduino or Raspberry Pi projects. Having a built-in power supply would make it much more convenient as you would just need a DC power adapter or a +9V battery to power everything up instead of adding additional wires for power and connecting it to an external power supply.

bookmark_borderLinux penguin PCB badge

I designed this pretty cool linux badge based on the linux penguin using KiCad and svg2shenzhen. There is no circuitry, just the a solder pad for a brooch pin. Feel free to checkout my github repo to get the design files https://github.com/Chromico/linux-penguin-PCB-badge . It’s open source so feel free to use it for whatever you want.

bookmark_borderHow to get started with FPGAs ( part 1 )

So just know that Iā€™m just a beginner in FPGAs but I want to write blog about how to get started with FPGAs so that I might help people that have no clue what an FPGA does or what an FPGA is. Iā€™m not gonna go into too much details about how an FPGA works but Iā€™m gonna only gonna tell what you need to know for now in order to do some cool stuff with FPGAs.

bookmark_borderMy experience during the 102 IETF hackathon in Mauritius

It was a Tuesday evening and Logan had asked on the GCI (Google Code-In) group if we wanted to take an Ubuntu challenge. He then informed us that we would be staying at Point aux Piments for 4 days but we had to work with TLS 1.3 which is the newest version of TLS. I accepted the challenge and agreed to come. Logan was kind enough to pick me up from my home and on the following day, I packed 4 sets of clothes, my laptop, my Bluetooth speaker, my towel, my phone, my phone charger and my toothbrush with a shaving kit as I do not like too much facial hair on my face. I asked Logan what time he was going to pick me up and he told me that it would be 7:00 in the morning.
