Special functions
Special test instrumentsCompact 8-channel logic analyzer for testing and analysing digital circuits; it plugs into the PC’s USB port so the captured data can be studied in detail. Maximum sampling rate 24 MHz. It supports 10 different communication standards: CAN, DMX-512, I²C, I2S/PCM, Manchester, 1-Wire, Async Serial, Simple Parallel, SPI, UNI/O. Fully compatible with the Saleae Logic software.
Raspberry PiExpansion shield module for Raspberry Pi, based on the 10-bit MCP3008 analogue-to-digital converter, which allows up to 8 input channels to be connected, each one on its own pin
Signal processingThe 8-channel I2C multiplexer based on the TCA9548A chipset is designed to expand the number of I2C devices that can be connected to an I2C bus. With a choice of 8 different I2C addresses, from 0x70 to 0x77, you can control up to 64 I2C devices by adding further multiplexers.
Radio remote controlsSelf-learning 8-channel 433MHz receiver compatible with Emylo remote controls. Up to 10 buttons can be learned for each channel. Monostable and bistable operation.
