You can adjust the output voltage... ## Pricing - **Price:** $25.25 (inc GST) — $22.95 AUD, exc GST - **Quantity discounts:** 10+ $22.04 (exc GST) · 25+ $21.35 (exc GST) ## Availability & dispatch - In stock, ships same business day if ordered before 2PM (Australia/Sydney). - We can dispatch 1 today, and up to 50 more in 7–12 days. ## How to buy - **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=PIM690:1` (comma-separated SKU:qty pairs) and share the link. Opening it shows a confirmation page with live pricing and stock before anything is added to the cart. - **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/PIM690:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.) - **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there. - **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works) - **Payment methods, purchase orders, policies and contact details:** https://core-electronics.com.au/llms.txt ## Description Output a variable voltage of up to 12V from your [Pimoroni Yukon](https://core-electronics.com.au/products/yukon) project, with this 5A step-down regulator. You can adjust the output voltage programmatically and in real-time! Use this to power devices that accept a **variable voltage** such as PC fans, and single colour LED strips. Alternatively, there is a "lock" trace on the underside that can be cut to **fix the output at 5V** regardless of the signal it is being given. In addition, there are two unpopulated digital IO signals exposed (with neighbouring 3.3V and GND pads) that can be used to connect up digital sensors to use as feedback. **Features**- TPS54A24 step-down converter ([datasheet](https://core-electronics.com.au/attachments/localcontent/tps54a24_232292f1afe.pdf)) - Adjustable 3V to 12V output\* - 5mm spaced screw terminals for attaching your output - 5A continuous current (10A peak) - 5V "lock" mode via cuttable trace - Exposed digital IO pads for feedback - Voltage, temperature and power good sensors - Fully-assembled - Soldering required for use of digital IO - Compatible with Pimoroni Yukon **Software**- [MicroPython Library Reference](https://github.com/pimoroni/yukon/blob/main/docs/modules/bench_power.md) - [MicroPython Examples](https://github.com/pimoroni/yukon/tree/main/examples/modules/bench_power) **Pinout and Schematic**[![](https://core-electronics.com.au/attachments/localcontent/bench_power_diagram_1024x1024_86800844798.png)](https://core-electronics.com.au/attachments/localcontent/bench_power_diagram_86800844798.png) - [Download a printable PDF version](https://core-electronics.com.au/attachments/localcontent/bench_power_diagram_997964fa8d3.pdf) - Schematic (coming soon) **Notes**- Measurements: 24mm x 20mm x 15.3mm (L x W x H). - \* To achieve the module's full output voltage range, Yukon's input voltage needs to at least 12V. For input voltages below 12V the module will only deliver up to that voltage on its output. - This module uses the RP2040's PWM hardware to control the output voltage. This means that only four modules can be used simultaneously, and they should be placed in Yukon Slots that do not share the same PWMs. - PWM 0B is on Yukon Slots 1 and 5 - PWM 2B is on Yukon Slots 2 and 6 - PWM 4B is on Yukon Slot 3 - PWM 6B is on Yukon Slot 4 **About Yukon**Yukon is a high-power modular robotics and engineering platform, built around Raspberry Pi's formidable RP2040 chip. It has slots for attaching interchangeable hardware modules for driving combinations of devices such as motors, servos, steppers, and LED strips, all from one board! Featuring an XT30 connector, Yukon can be directly powered off 2 to 4 cell LiPo batteries (or any other 5 to 17V source), to deliver up to 15A continuous for your high-power projects. An e-Fuse with switchable output protects the board, along with voltage, current, and temperature sensors that can be monitored by your programs.
