$5 CH347 board is a USB 2.0 bridge to I2C, SPI, UART, JTAG, and GPIO

small CH347 development board

MuseLab USB-HS-Bridge is an inexpensive ($5) board based on WCH CH347 chip with a USB 2.0 Type-C interface that acts as a bridge for I2C, SPI, UART, and JTAG interfaces, as well as GPIOs. It’s notably useful to debug and download bitstreams to FPGA development boards, but it can also be used to connect various peripherals such as I2C sensors, SPI flash devices, UART devices to basically any host with a spare USB 2.0 host port. USB-HS-Bridge specifications: Chip – WCH CH347 high-speed USB to UART, I2C, SPI and JTAG chip (See link to the datasheet for details) USB – 1x USB 2.0 Type-C port with up to 480 Mbps data rate I/Os – 2x 16-pin header with 2x UART interfaces up to 9 Mbps baudrate 1x I2C for EEPROM or sensors 1x SPI master interface with 2 chip select signals to control up to 2x SPI slave devices.

HiPo batteryless NFC-powered 3.52-inch e-Paper display also comes with an SPI interface (Crowdfunding)

HiPo display NFC reader

HiPo is a 3.52-inch black and white e-Paper Display that can be updated through NFC without the need for external power and offers an alternative to the 4.2-inch and 7.5-inch NFC-powered e-Paper displays from Wareshare that also operate without battery only using the data and power from NFC to update the image. Alternatively, Guangdong SID Technology’s HiPo display can also be connected to an SPI adapter board allowing the users to connect it to an STM32 board provided by the company, but it could also be used with Arduino boards, ESP8266 & ESP32 hardware platforms, Raspberry Pi SBCs and MCU boards, or any platform with an SPI interface. HiPo specifications: Controller – Ultrachip UC8251 all-in-one driver IC with timing controller for E-tag applications Display 3.52-inch B&W e-Paper display with 360 x 240 resolution (model name: SE0352N01-MNG-A0) 3 seconds refresh time On-chip display RAM White reflectance above 30% Contrast ratio above […]

xSPI MRAM provides an alternative to SPI NOR/NAND flash with up to 400MB/s R/W bandwidth

Everspin xSPI MRAM block diagram

Everspin has unveiled the EMxxLX xSPI MRAM (Magnetoresistive Random Access Memory) non-volatile memory solution for industrial IoT and embedded systems providing an alternative to SPI NOR/NAND flash with much faster R/W data rates of up to 400MB/s and densities between 8Mbit and 64Mbit. The higher speed is made possible by the new JEDEC expanded Serial Peripheral Interface (xSPI) standard interface and a clock frequency of up to 200 MHz, the maximum supported by the xSPI standard. All chips operate at 1.8V, and the family is offered in 24-ball BGA and 8-pin DFN packages. EMxxLX xSPI MRAM key features and specifications: Density – 8Mb, 16Mb, 32Mb, 64Mb 400MBps sustained throughput with OSPI at 200MHz, DTR, for reads and writes Expanded SPI (xSPI) bus interface supporting Octal, Quad, Dual, and Single SPI protocol Up to 200MHz single and double transfer rate (STR/DTR) for Octal SPI Up to 133MHz, SPI, DSPI, QSPI Data […]
