Development Boards

The Au continues the trend of more affordable and increasingly powerful FPGA boards arriving each year. This board is a fantastic starting point into the world of FPGAs and the heart of your next project. Finally, now that SparkFun builds this board, we added a Qwiic connector for easy I²C integration! The Alchitry Au features a Xilinx Artix 7 XC7A35T-1C FPGA with over 33,000 logic cells and 256 MB of DDR3 RAM. The Au offers 102 3.3 V logic level IO pins, 20 of which can be switched to 1.8 V; Nine differential analogue inputs; Eight general-purpose LEDs; a 100 MHz on-board clock that can be manipulated internally by the FPGA; a USB-C connector to configure and power the board; and a USB to serial interface for data transfer. To make getting started even easier, all Alchitry boards have full Lucid support, a built-in library of useful components to use in your project, and a debugger! Features Artix 7 XC7A35T-1C - 33,280 logic cells 256 MB DDR3 RAM 102 IO pins (3.3 V logic level, 20 of them can be switched to 1.8 V for LVDS) Nine differential analogue inputs (One dedicated, Eight mixed with digital IO) USB-C to configure and power the board Eight general-purpose LEDs One button (typically used as a reset) 100 MHz on-board clock (can be multiplied internally by the FPGA) Powered with 5 V through USB-C port, 0.1' holes, or headers USB to serial interface for data transfer (up to 12 Mbaud) Qwiic Connector Dimensions: 65 x 45 mm

The SparkFun RP2040 mikroBUS Development Board is a low-cost, high performance platform with flexible digital interfaces featuring the Raspberry Pi Foundation's RP2040 microcontroller. Besides the Thing Plus or Feather PTH pin layout, the board also includes a microSD card slot, 16 MB (128 Mbit) flash memory, a JST single cell battery connector (with a charging circuit and fuel gauge sensor), an addressable WS2812 RGB LED, JTAG PTH pins, four (4-40 screw) mounting holes, our signature Qwiic connectors, and a mikroBUS socket. The mikroBUS standard was developed by MikroElektronika. Similar to Qwiic and MicroMod interfaces, the mikroBUS socket provides a standardized connection for add-on Click boards to be attached to a development board and is comprised of a pair of 8-pin female headers with a standardized pin configuration. The pins consist of three groups of communications pins (SPI, UART and I²C), six additional pins (PWM, Interrupt, Analog input, Reset and Chip select), and two power groups (3.3 V and 5 V). The RP2040 is supported with both C/C++ and MicroPython cross-platform development environments, including easy access to runtime debugging. It has UF2 boot and floating-point routines baked into the chip. While the chip has a large amount of internal RAM, the board includes an additional 16 MB of external QSPI flash memory to store program code. The RP2040 contains two ARM Cortex-M0+ processors (up to 133 MHz) and features: 264 kB of embedded SRAM in six banks 6 dedicated IO for SPI Flash (supporting XIP) 30 multifunction GPIO: Dedicated hardware for commonly used peripherals Programmable IO for extended peripheral support Four 12-bit ADC channels with internal temperature sensor (up to 0.5 MSa/s) USB 1.1 Host/Device functionality Features (SparkFun RP2040 mikroBUS Dev. Board) Raspberry Pi Foundation's RP2040 microcontroller 18 Multifunctional GPIO Pins Four available 12-bit ADC channels with internal temperature sensor (500kSa/s) Up to eight 2-channel PWM Up to two UARTs Up to two I²C buses Up to two SPI buses Thing Plus (or Feather) Pin Layout: 28 PTH Pins USB-C Connector: USB 1.1 Host/Device functionality 2-pin JST Connector for a LiPo Battery (not included): 500mA charging circuit 4-pin JST Qwiic Connector LEDs: PWR - Red 3.3V power indicator CHG - Yellow battery charging indicator 25 - Blue status/test LED (GPIO 25) WS2812 - Addressable RGB LED (GPIO 08) Buttons: Boot Reset JTAG PTH Pins 16MB QSPI Flash Memory µSD Card Slot mikroBUS Socket Dimensions: 3.7' x 1.2' Four Mounting Holes: 4-40 screw compatible Downloads Schematic Eagle Files Board Dimensions Hookup Guide Qwiic Info Page GitHub Hardware Repository
