About the Vanchor thrust PCB

Vanchor thrust is an open source RP2040/RP2350 PCB design by AlexAsplund, published on GitHub. It is a 2-layer board measuring 95 × 92 mm, with 33 components from 20 distinct parts.

Its main chip is the Pico 2 (DNP), from the RP2040/RP2350 family. Other key parts include the BTN8982TA and R-78E5.0 (DNP). By type, the board carries 13 resistors, 7 connectors, 6 ICs, 5 capacitors and 2 diodes.

It belongs with the power & battery designs in this gallery.

From the project

95×92 mm 2-layer board. Full H-bridge for a 12–24 V brushed trolling motor, controlled by the vanchor-helm board over one straight 8-wire cable. Two build variants share the same PCB:

J1 mirrors helm J13 pin-for-pin — crimp a straight 8-wire cable (0.5–1 mm², keep it under ~2 m, twist RPWM/LPWM with GND spares if longer):

The LED (D1) lights when the helm's 5 V arrives — a quick cable check.

Vanchor thrust: common questions

What microcontroller does the Vanchor thrust use?

The Vanchor thrust is built around the Pico 2 (DNP), from the RP2040/RP2350 family.

How big is the Vanchor thrust PCB?

The Vanchor thrust measures 95 × 92 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Vanchor thrust?

33 components, from 20 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Vanchor thrust design files?

From the AlexAsplund/vanchor-pcb repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Vanchor thrust design in my own project?

The repository has no license, so all rights stay with AlexAsplund. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Vanchor thrust without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
