INK4u Board
About the INK4u Board
INK4u Board is an open source PCB design by TheEccentricGenius, published on GitHub under the CERN-OHL-W-2.0 license. It is a 2-layer board measuring 68.6 × 53.3 mm, with 59 components from 39 distinct parts.
Other key parts include the LMV358, CH340E, AVR128DA28x-xSP, AMS1117-5.0 and AMS1117-3.3. By type, the board carries 12 capacitors, 11 resistors, 8 connectors, 7 diodes, 6 ICs and 3 jumpers.
It belongs with the usb & debug tools designs in this gallery.
From the project
An UNO form factor board with a AVR128DA28 processor.
An UNO form factor board with a AVR128DA28 processor.
This board is designed to be the next generation AVR succesor to the UNO R3 using the AVR128DA28 from Microchip.
The board has a number of features, such as a UPDI programming and UART programming onboard. The on-board UPDI programming means a bootloader can be burned onto the MCU while it is on the board....No more external programmer required for programming via the ISP header!
