VoxLink Programmer Board
About the VoxLink Programmer Board
VoxLink Programmer Board is an open source PCB design by MichalVarsanyi, published on GitHub under the MIT license. It is a 4-layer board measuring 49.1 × 15.5 mm, with 55 components from 40 distinct parts.
Other key parts include the TPD4E02B04, LTC4368, XT30 and TPS82084. By type, the board carries 20 resistors, 19 capacitors, 5 ICs, 5 diodes, 3 connectors and 2 inductors.
It belongs with the sensors and usb & debug tools designs in this gallery.
From the project
VoxLink is a high-speed solution that allows interfacing of up to 100 sensors using a single high-speed host device. The communication protocol is agnostic to the sensor board, freeing the user from handling low-level communication. This project is part of my Bachelor's thesis at the Czech Technical University in Prague.
- During programming, exceeding internal clocking speeds of 100MHz on the iCE40UL1K-CM36AI FPGA proved to be virtually impossible. In the future, instantiating the hard IP I2C blocks in the FPGA silicon may increase the speed. Realistically, however, switching to a higher speed grade of FPGAs will probably be the best option.
It may seem that 50-100 MHz is unreasonably fast; however, just 40 sensors at 9 kHz get very close to this ballpark. It is difficult to determine what may increase the bandwidth in the future, so it's better to have an excess than to have too little bandwidth.…
