We already have a fair choice of boards with Arduino compatible headers powered by an FPGA with options such as $99 Digilent Arty (Xilinx Artix-7 FPGA), FleaFPGA (Lattice FPGA), Papillio DUO (Xilinx Spartan 6), or Snickerdoodle + shieldBuddy (Xilinx Zynq-7010/20). There’s no yet another choice with Alorium Technology XLR8 Arduino UNO like board powered by Altera MAX10 FPGA.
XLR8 board specifications:
- FPGA – Altera MAX 10 FPGA
- MCU – Atmel/Microchip ATmega328 8-bit MCU
- Digital I/Os
- 5V inputs, 3.3V outputs
- 14x Digital I/O Pins
- 6x PWM Digital I/O Pins
- 6x Analog Pins
- Analog Inputs
- 5V tolerant
- Op-amp circuit emulates 0-5V behavior of the ADCs on the Arduino UNO
- Performance: 1 MHz;
- Resolution: 12-bit sustained
- Sample Rate: 154k samples/second
- Power Supply – 5V via USB or barrel connector
- Dimensions – Arduino UNO form factor
The board is supported by Altera Quartus Prime Lite Edition, and programmable either via JTAG though a USB blaster, or USB with OpenXLR8 and Arduino IDE without additional hardware as shown in the diagram below.
The FPGA can be programmed with what the company called Xcelerator Blocks (XB), an optimized hardware implementation of a specific processor intensive function, with functions such as Floating-point math, servo control, or NeoPixel shields, strips, and arrays control currently available. Future implementations likely to be worked on include: Proportional-Integral-Derivative (PID) control, event counters and timers, quadrature encoders/decoders, PWM, multiple UARTs, and enhanced Analog-to-Digital (ADC) functionality.
