SPARKFUN QUICKLOGIC THING PLUS FEATURING EOS S3 MCU AND EFPGA IS NOW AVAILABLE AT $45.95

SparkFun QuickLogic Thing Plus was originally crowdfunded on CrowdSupply that raised around $4500. If you did not back the product back then, no worries, you can buy it now on the SparkFun product page. SparkFun QuickLogic Thing Plus is a powerful FPGA board that comes with a Feather-footprint. The product from the collaboration of SparkFun and QuickLogic makes it a rapid prototyping open-source hardware with ultra-low power SoC for power-sensitive applications.

This FPGA board is built around QuickLogic’s EOS S3 MCU + eFPGA SoC featuring embedded FPGA (eFPGA) technology with 2,400 effective logic cells. The Arm Cortex-M4F MCU provides 512 KB of RAM. One of the important features to note is the out of the box support for machine learning algorithms with TensorFlow Lite and SensiML. However, since it has eFPGA, the software support in that regard is SymbiFlow and Renode.

Specification Of SparkFun QuickLogic Thing Plus:

  • CPU: QuickLogic EOS S3 MCU + eFPGA SoC featuring Arm Cortex-M4F MCU running at up to 80 MHz
  • Form factor: Breadboard-compatible 0.1‚Ä≥ (2.54 mm) pitch headers ‚Äď all headers are pre-soldered
  • Dimensions: 2.75‚Ä≥ x 0.9‚Ä≥ (70 mm x 22.9 mm) footprint
  • Storage: 16 Mbit SPI NOR flash
  • Sensors: Accelerometer, Digital pulse density modulation (PDM) microphone
  • Interfaces: SWD programming connector, UART, I¬≤C, I¬≤S, SPI
  • Power supply: USB Type-C connector or via Li-Po battery

As mentioned earlier, the QuickLogic EOS S3 SoC is an ultra-low-power chip, so the board can be powered using a Li-Po battery as well with onboard charging circuitry using the Microchip MCP73831/2 and has a standard Li-Po JST connector. When it comes to ML applications, it is always an added advantage when there are sensors onboard. So, to solve this the designer has provided the board with an accelerometer with STMicro LIS2DH12TR and digital pulse density modulation (PDM) microphone with Wake-on-Sound (WoS) feature through the Vesper VM3011-U1.
