LaskaKit USB-C adapter

Product detailed description

The LaskaKit USB-C adapter breaks out power and data lines from a USB-C connector to 2.54 mm pitch solder pads and a 4-pin μSup (JST-SH) connector. It is suitable for connecting your own PCB, microcontroller, or a breadboard project to a computer or USB charger – for example, as a replacement for a damaged or outdated USB connector. The CC pins are equipped with 5.1 kΩ pull-down resistors, so the adapter acts as a sink, allowing a standard USB-C source to provide 5 V up to 3 A. TVS diodes protect both the power supply and data lines.

Specifications:

• Sales Version: v1.1
• Connector: USB-C (female)
• USB-C Mode: sink, 5.1 kΩ pull-down resistors on CC1 and CC2
• Power Supply:
  • Output Voltage: 5 V (VBUS directly from source)
  • Max. Power: 15 W (5 V / 3 A) according to CC signalling
• Protection: TVS diodes with a breakdown voltage of 5.6 V
• Pins:
  • Solder pads (2.54 mm pitch): 2× triplets of GND, VBUS, D− and GND, VBUS, D+
  • µŠup Connector (JST-SH 4-pin, 1 mm pitch): D–, D+, VBUS, GND
• Mounting: 2 mounting holes
• Dimensions:
  • Board: 21 × 20 mm
  • Height: 5 mm (including USB-C connector)
• Suitable for:
  • Dupont Pin Header 40-Pin 2.54 mm
  • µŠup JST-SH 4-pin Cable – 10 cm
  • µŠup JST-SH 4-pin Cable – Dupont Male
  • µŠup JST-SH 4-pin Cable – Dupont Female
  • Solderless Breadboard 400 Pins

Important wiring notice:

• The µŠup connector uses the same JST-SH 4-pin cables as I2C modules, but it carries USB signals (D–, D+, VBUS, GND) instead of I2C. You can therefore use standard µŠup cables for connection, but do not connect the adapter to the µŠup/I2C connector of other modules and boards – 5 V would reach their pins, risking damage.
• The adapter does not support USB Power Delivery or Quick Charge – even a "smart" charger will always provide only 5 V. For higher voltages, use the LaskaKit USB-C PD CH224K Power Voltage Switch.
• The adapter operates in sink mode only. It cannot be used as a source to power other USB-C devices.
• As a USB connector replacement (e.g. for Arduino), connect VBUS, D+, D– and GND to the corresponding pins of the original connector. No software modification is required. Keep the D+ and D– data wires as short as possible.
• The JST-SH connector is rated for approx. 1 A. For higher current draw, use the solder pads.
