The iCEBreaker FPGA board is an open-source educational FPGA development board. The iCEBreaker is great for classes and workshops teaching the use of the open source FPGA design flow through Yosys, nextpnr, IceStorm, Icarus Verilog, Amaranth HDL and others. This means the board is low cost and has a nice set of features to allow for the design of interesting classes and workshop exercises. At the same time it allows the user to use the proprietary vendor tools if they choose to. After the workshop the boards can be easily used as a development board as most GPIO are exposed, broken out and configurable through jumpers on the back of the board. There is only a minimal amount of buttons and LED that can't be disconnected and used for your own purposes. Documentation Workshop

The DiP-Pi Power Master is an Advanced Powering System with embedded sensors interfaces that cover most of possible needs for application based on Raspberry Pi Pico. It can supply the system with up to 1.5 A @ 4.8 V delivered from 6-18 VDC on various powering schemes like Cars, Industrial plant etc., additionally to original micro-USB of the Raspberry Pi Pico. It supports LiPo or Li-Ion Battery with Automatic Charger as also automatic switching from cable powering to battery powering or reverse (UPS functionality) when cable powering lost. Extended Powering Source (EPR) is protected with PPTC Resettable fuse, Reverse Polarity, as also ESD. The DiP-Pi Power Master contains Raspberry Pi Pico embedded RESET button as also ON/OFF Slide Switch that is acting on all powering sources (USB, EPR or Battery). User can monitor (via Raspberry Pi Pico A/D pins) battery level and EPR Level with PICO’s A/D converters. Both A/D inputs are bridged with 0402 resistors (0 OHM) therefore if for any reason user needs to use those Pico pins for their own application can be easy removed. The charger is automatically charging connected battery (if used) but in addition user can switch charger ON/OFF if their application needs it. DiP-Pi Power Master can be used for cable powered systems, but also for pure Battery Powered System with ON/OFF. Each powering source status is indicated by separate informative LEDs (VBUS, VSYS, VEPR, CHGR, V3V3). User can use any capacity of LiPo or Li-Ion type; however, must take care to use PCB protected batteries with max discharge current allowed of 2 A. The embedded battery charger is set to charge battery with 240 mA current. This current is set by resistor so if user need more/less can himself to change it. In Addition to all above features DiP-Pi Power Master is equipped with embedded 1-wire and DHT11/22 sensors interfaces. Combination of the extended powering, battery, and sensors interfaces make the DiP-Pi Power Master ideal for applications like data logger, plants monitoring, refrigerators monitoring etc. DiP-Pi Power Master is supported with plenty of ready to use examples written in Micro Python or C/C++.

This is a long-wave IR thermal imaging camera that adopts the hybrid technology of microbolometer and thermopile pixel, features 80x62 array pixels. It will detect the IR1 distribution of objects in the field of view, turn the data into surface temperature of the objects by calculation, and then generate thermal images, for easy integration into miscellaneous industrial or intelligent control applications. Features Adopts the hybrid technology of microbolometer and thermopile, 80x62 array pixels Continuous operation and thermal imaging video stream due to shutterless design Noise Equivalent Temperature Difference (NETD) 150mK RMS@1 Hz refresh rate Up to 25 fps (Max) thermal imaging video stream output Comes with online resources and manuals (Python demo for Raspberry Pi, Android/Windows host computer and user manual, etc.) Applications High precision long-term non-contact temperature online monitoring IR thermal imaging devices, IR thermometers Smart home, intelligent building, intelligent lighting Industrial temperature control, security & safety, intrude/motion detection Small Target Thermal Analysis, Heat Trend Analysis and Solutions Specifications Power supply 5 V Operating current 61 mA@5 V Wavelength range 8~14 μm Operating temperature -20~85°C Target temperature -20~400°C Refresh rate 25 fps (Max) FOV 45° x 45° (H x V) Noise equivalentTemperature diffenerence 150 mK Measuring accuracy ±2°C (ambient temp. 10~70°C) Dimensions 65.0 x 30.5 mm Included 1x Thermal Camera HAT 1x 40-pin female header 1x FPC 15-pin cable 0.3 mm pitch (100 mm) 1x Screws pack Downloads Wiki
