Breakout board based on the Texas Instruments BQ76920 integrated circuit designed for charging and discharging 3-cell lithium battery packs. The board can be managed by any programmable processor (for example Arduino with the provided libraries). Thanks to a special library, it is possible to measure and communicate, via I2C bus, the amount of charge (Coluomb) transferred to the battery. The board is equipped with a 10k NTC type temperatur
Let’s substitute our 3D printer’s command panel with a dot-matrix that enables the display of graphics, function icons and animations. We would like to remind you that our 3Drag printer (that prints plastic items of the size of 200x200x200 mm) may be supplied with a command panel, so to locally manage the printing…
On the hardware of the controller board LED Matrix, by taking advantage of the reconfigurability of the onboard FPGA, we can build a bivalent tool that is extremely useful to have on our work bench. If you’re looking for a tool for measuring frequency that is not the classic multimeter and, in the various…
Development platform based on Espressif’s ESP32 chip, a 32-bit Dual-Core Tensilica LX6 microcontroller with a 240 MHz clock frequency, 520 kB internal SRAM memory, Wi-Fi 802.11 b / g / n , Dual-mode Bluetooth (classic and BLE) and 28 I / O pins. On the board there is also a 32…
A small jewel capable of detecting atmospheric pressure and temperature, designed for the construction of weather stations or applications where it is important to know these parameters, such as air mass meters and altimeters. Let’s try it with Arduino. We know Omron for the many industrial sensors it has produced and continues to…
This PCB Etching Kit System is easy to use and easy to assembly. The printed circuit board etching tank features graduated markings to assist in setting appropriate etchant depth. Normal usage requires a minimum of 2 liters of etching solution. The system includes some handy wire clips used to hang your PCB(s) in…
Small module for Raspberry Pi with 8-megapixel Sony IMX219PQ image sensor and 1/4 “fixed lens. Able of taking photos with a resolution of 3280×2464 pixels, can shoot HD video in 1080p format at 30 fps (720p at 60 fps), making it possible for users of Raspberry Pi boards to create video applications and try time-lapse…
