Snickerdoodle Black (Connectors Up)

Added to your shopping cart

krtkl’s Snickerdoodle Black system-on-module (SoM) is a Zynq-based computer module with dual-band Wi-Fi, BLE, 1GB RAM, 16MB flash, 180 I/O, an SD card cage, and is the size of a business card. Built on a Xilinx® Zynq™-7020 system-on-chip (SoC) and a Texas Instruments WiLink™ 8 wireless module, Snickerdoodle is designed to make high-performance, power-efficient computing and artificial intelligence (AI) at the network edge practical, affordable, and scalable.

The 2.0" x 3.5" (50.8mm x 88.9mm) board offers a Zynq SoC with two 866MHz Arm® Cortex®-A9 cores and a 1.3M gate Xilinx Artix®-7 field-programmable gate array (FPGA), dual-band Wi-Fi and BLUETOOTH® Low Energy connectivity, 1GByte of LPDDR2 RAM, 125 reconfigurable FPGA inputs/outputs (I/O), and 55 additional I/O pins. Out of the box, Snickerdoodle supports Ubuntu Linux, Python, PYNQ, C/C++, and bare metal. Every Snickerdoodle black includes an adhesive-backed copper heat sink.

Snickerdoodle Black is offered in two variants for design flexibility: The Connectors Down variant (DEV-18098) features bottom-mounted headers, while the Connectors Up variant (DEV-18100) features top-mounted headers.
