Description

SPI/UART/I2C bridge with USB interface

The ElmorLabs EVC2 aims to enable DIY users to get more out of their computer parts. It’s main focus is enabling digital or analog voltage control using I2C/SMBus/PMBus but also has UART and SPI functionality. The latest version is called the EVC2SE and has improved signal margin, finer adjustment control and different connectors with better mechanical connection to the PCB.

Specifications

  • 3x I2C headers working at 3.3V (5V tolerant)
  • 1x UART header, 3.3V (5V tolerant)
  • 1x SPI header with 3.3V supply enable/disable (5V tolerant)
  • VMOD header for voltage sense and feedback adjustments (3x voltage reading, 3x current source/sink)
  • Built-in USB bootloader for firmware updating
  • Firmware and software compatible with EVC2N/EVC2S/EVC2SX (L4 firmware version)

Included accessories

  • USB cable Type-C to Type-A 100cm
  • 1x 3-pin JST XT to 3-pin JST XH 40cm (I2C/UART)
  • 2x 3-pin JST XT to open end cable 40cm (I2C/UART)
  • 1x 2-pin 2.54mm to open end cable 40cm (VMOD)
  • 1x 1-pin 2.54mm to open end cable 40cm (Ground)
  • 20-pin splittable 2.54mm to 2.54mm jumper wires 30cm
  • 2x 1×10-pin 2.54mm through-hole header strip
  • 20-pin splittable 2.0mm to 2.54mm jumper wires 20 cm
  • 1x 1×10-pin 2.54mm surface-mount header strip

Optional accessories

Key differences compared to EVC2SX

  • Headers for I2C1/I2C2/UART changed from 2.54mm pitch pin headers to JST XH headers
  • Improved I2C1 performance at 400 KHz
  • Added fine-grain adjustments for SRC1/SRC2 DAC channels (0.01µA steps at Vfb = 0.6V)
