Arduino has been traditionally dominated by Microchip-Atmel chips. The Uno uses a 8 bit AVR, and the newer boards have a 32 bit SAMD21 ARM core. Enters a new alternative, code name “blue pill”; and it’s fantastic! What is the STM32 Blue Pill? The STM32 “Blue Pill” is a development […]
Today we are reviewing the PCBs made by JLCPCB. JLCPCB is one of the bigger Shenzhen based PCB manufacturers out there. Although questionable, they claim to get over 8000 orders per day. More recently they got a lot of community support by partnering up with EasyEDA; but they also made […]
I am currently designing a big VFD tube IoT thing and when creating the PCB I sent the gerber files to OshPark. They quoted back about US$180. Ouch. OshPark pricing completely breaks down once you start marking a board 4 inches / 10 cm long or above. So to China […]
There are many different kind of ESP32 boards out there; but the DOIT is by far the most popular one. It’s simple: if you type ESP32 in Banggood, Aliexpress or Taobao, it is the first design that comes up. Quite simply, if you are starting with ESP32, it is […]
The Arduino Mega is a great board. You can often get a project that typically requires multiplexing or shift registers running with a single Mega board because it contains so many GPIOs. The only problem I have with it is its massive size. Enters Robotdyn shrunk versions, and for about […]
Robodyn is one of the few Chinese companies that managed to make a name for itself. They produce high quality Arduino clones and various electronics modules. Today we review their DS1307 real time clock module. Shop webpage: https://www.aliexpress.com/store/1950989 General presentation The first thing you’ll notice about this real time clock […]
Robotdyn is one of the few Chinese companies that managed to make a name for itself. They produce high quality Arduino clones and various electronics modules. Today we review their 24 steps rotary encoder module. Shop webpage: https://www.aliexpress.com/store/1950989 Rotary encoder The first thing that pops of course is the price […]
Wireless communication a few years back was the exclusive playground of RF (radio frequencies). Then it exploded: Nordic, Wifi, Bluetooth, Zigbees… Today there are lots of options available. Simple RF modules though, are still popular and Synoxo has managed to incredibly shrink them to a few millimeters; while still retaining their […]
