Hw module xesc

hw-module-xesc

A breakout/carrier module for the xESC2 mini brushless motor controller, designed for stand-alone use outside of a larger mainboard.

What This Is

The xESC2 mini is a small, low-cost FOC motor controller for BLDC motors (10 A / 40 V continuous). It ships as a bare module with pin headers — it expects 5 V logic from a host board.

This carrier PCB makes the xESC2 mini usable stand-alone by adding:

• Onboard DC/DC converter (LV2862XDDC) — generates 5 V from the main battery voltage, so no external logic supply is needed
• Screw terminals — for battery power input and motor phase wires
• Transient voltage protection (SMCJ33CA TVS diode)
• Decoupling capacitors and supporting passives

The 5 V DC/DC and its protection diode are optional — if you integrate the xESC2 into a larger system that already supplies 5 V, those parts can be omitted to save cost and board space.

Building / Ordering

Use the files in release/ to order from JLCPCB (or any compatible fab):

1. Upload hw-module-xesc-JLCPCB.zip as the Gerber file.
2. Enable PCB assembly and upload hw-module-xesc_bom_jlc.csv and hw-module-xesc_cpl_jlc.csv.
3. Solder the xESC2 mini module onto the pin headers.
