Pygmy [वामन (VAMAN in Hindi)] Stamp Board is an affordable module based on the QuickLogic EOSS3 - an Ultra Low Power MCU + eFPGA SoC.
A Tiny 21mm(L) x 9mm(W) x 1.2mm(H) module, with castellated holes, 54 pads with all EOSS3 pads broken out.
On-Board 16Mbit SPI Flash and EOSS3 Bootstraps, allowing flexible use in any scenario.
1 mm pitch castellated pads make it easy even for hand-soldering.
QuickLogic Open Reconfigurable Computing (QORC) is the first project in the world to embrace
the completely open source Symbiflow Toolchain for FPGAs effort, with all the FPGA internals open sourced.
QORC targets the EOSS3 SoC which has a Cortex-M4 core + eFPGA tightly integrated and accessible from the Cortex-M4 core via an open source Wishbone bus.

OptimusLogic is happy to partner with QuickLogic to support the QORC Initiative
The Pygmy Stamp Board was created in collaboration with QuickLogic to lower the entry barrier for usage of the EOSS3 - ranging from simple academic development kits to complex commercial usage, without getting into expensive and complex process of making BGA design/manufacturing.
OptimusLogic makes a low cost development board, Pygmy Base Board v1, a medium cost development board with on-board WiFi/BT/BLE connectivity, Pygmy Base Board v2, as well as a completely open source watch form-factor development kit, Sensei, leveraging the Pygmy module.
The Pygmy BB0 is a minimal development board based around the Pygmy Stamp module, and aims to be a drop-in low-cost replacement of the QuickFeather development board, with the BMX160 as the IMU, and 2x PDM Mics.
Additionally, it adds in an nRF52840 module + 64Mbit QSPI Flash + μSD card storage support, making it a perfect fit for low-power wireless ML/IoT node development. The native USB capability of the nRF52840 can be realized using the dedicated μUSB port on the BB0.
The Pygmy BB4 is a development board based around the Pygmy Stamp module, and brings on-board WiFi/BT/BLE connectivity with ESP32, as well as an 18650 battery option, μSD Card (connected to ESP32), possibility to use EOSS3 in smartphone mode with the ESP32 as the Host, and all EOSS3 pins accessible.
A BMX160 provides an AMG IMU, supplemented by a BNO055 smart fusion sensor. A DPS310 provides Pressure, Humidity and Temperature monitoring.
The Sensei Lite is a compact wearable form factor development board based around the Pygmy Stamp module, with the addition of the nRF52832 for BT/BLE connectivity. It is designed in to use the EOSS3 in the Smartphone/Companion Mode, and the nRF52832 acts as the Host.
A single PDM Mic (as well as debug connectors to the board) can be optionally soldered on to the Pygmy Module pins to bring out extra lines as needed - these are not on the board itself, to maintain a compact (band) form factor.
The Sensei is a wearable form factor development board packed with sensors, and designed for maximum flexibility for development and debug, while still maintaining a small(ish) size.
It is based around the Pygmy Stamp module, with the addition of a nRF52840 module for BT/BLE connectivity.
It is designed in to use the EOSS3 in the Smartphone/Companion Mode, and the nRF52840 acts as the Host, but can also use the EOSS3 standalone. It also features a 1.3" Touchscreen (TFT + CTP)
