First Steps with the Tang Nano FPGA Development Board

The Tang Nano is a very very low cost FPGA development board by Sipeed featuring a GW1N-1-LV FPGA produced by GOWIN Semiconductors. GOWIN is another Chinese chip manufacturer entering the FPGA arena, like Efinix and Anlogic.
The GW1N-1-LV is the smallest member of GOWINs “Little Bee” series, which consists of small footprint instant-on FPGA devices for IoT and interfacing solutions.

Gigabit Transceiver(s) for a Cheap FPGA Development Board

There are a lot of FPGA development boards out there to buy. Official vendor boards with the latest advanced devices on it can easily cost several thousand Euros.
Hobbyists and makers are more interested in FPGA development boards within an affordable price range (roughly << 100 $/€). The logic resources and feature set of the FPGA devices on these boards is not that important on the other hand. The main application for makers/hobbyists is small projects and self-learning, I assume, and not rolling out their own 5G equipment.

Electronics 101: Standard Resistor Values

When we learn the theory behind electronic circuits we often calculate the exact value a certain resistor, capacitor or inductance should have.

However, in reality there is no 23.94 Ohms resistor available as standard off-the-shelf (SOTS) electronic part. Go and check it if you don’t believe me.
