BeagleBoard.org has posted a product page for the BeagleConnect QuadESC, an open-source four-channel brushless-DC (BLDC) motor-control board aimed at robotics and multirotor propulsion. The board is 60 x 48 mm and has four complete three-phase power stages. It is controlled by a new solder-down module, the BeagleConnect Torque, which carries Texas Instruments' AM13E23019 microcontroller. LinuxGizmos covered the board on October 25, 2026.
Read the spec sheet carefully, because BeagleBoard.org is open about what is still unfinished. The headline current figures are design targets, not validated ratings. The board also ships without motor-control firmware, so out of the box it does not spin anything.
The controller: BeagleConnect Torque and the AM13E23019
The BeagleConnect Torque product page describes the module as a compact open-source controller measuring 25.4 x 38.1 mm. It mounts through a 100-pad solder-down interface and has onboard CAN, Qwiic and expansion connections. On the QuadESC it is the central controller, and BeagleBoard.org says the Torque module comes installed.
The QuadESC product page lists these specs for the MCU:
- TI AM13E23019, 200 MHz Arm Cortex-M33
- 512 KB flash, 128 KB SRAM
- Floating point and a trigonometric math unit
- TinyEngine neural-network accelerator
- Three 12-bit ADCs
- TCAN844 CAN transceiver (on the Torque module)
TI's AM13E23019 product page marks the part as NEW and PREVIEW and describes it as a "200MHz Arm Cortex-M33 real-time motor control MCU with edge AI, TMU, 512KB flash, security." TI links an AM13E230x datasheet (Rev. A) from that page. PREVIEW is TI's own label, so anyone thinking about a derivative design should check the part's current status with TI before committing to it.
The power side: four DRV8323 drivers, twelve half-bridges
The power architecture on the QuadESC is conventional, and that is a good thing. BeagleBoard.org lists:
- Four TI DRV8323SRTAR gate drivers with integrated current-sense amplifiers, configured over SPI
- Twelve TI CSD88599Q5DC half-bridge devices, three per motor across four three-phase channels
- A TPS54360B buck regulator and a TPS7A4701 analog regulator
LinuxGizmos adds two details about the topology. All four gate drivers share one SPI bus with individual chip-select signals, and two common enable signals gate all four power stages together. In practice firmware addresses each driver individually for configuration, but the power stages are enabled or disabled as a group.
Sensing: 29 analog signals
The board is heavily instrumented for its size. The product page lists twelve low-side current-sense signals, twelve divided phase-voltage signals, four board-temperature sensors and a battery-voltage measurement. LinuxGizmos counts these as 29 analog signals in total. With phase voltage and phase current available on every channel, the hardware provides a foundation for field-oriented control (FOC). Whether it actually does FOC depends on the firmware, as explained below.
Ratings: read the qualifiers
BeagleBoard.org gives the intended input as 3S to 6S, 9 to 25.2 V. LinuxGizmos reports that the hardware documentation identifies a 32 V design maximum and notes that this figure is not a recommended operating supply. The 9 to 25.2 V range is the one the maker states as intended.
The per-motor current figures are 40 A continuous and 70 A burst. The product page labels them design targets "subject to thermal validation," and states that a burst duration has not been specified. That leaves the 70 A figure without a time base, so it cannot be compared directly with the burst ratings of off-the-shelf ESCs. LinuxGizmos likewise says these figures have not been established as validated operating ratings. Until BeagleBoard.org publishes thermal results, treat them as goals.
Flight-controller interface and debug
The QuadESC connects to a flight controller through an eight-pin interface. According to the product page it carries four command routes, telemetry, current reporting, battery power and ground. LinuxGizmos reports that the command signals are DShot and that the board has an ARM/JTAG debug header with SWD support. BeagleBoard.org documents programming and debug setup using TI's XDS110 tools.
Firmware: bring your own
This is the most important caveat. The product page says the factory ROM provides TI's bootstrap loader and that suitable application firmware must be loaded before operating motors. FOC, DShot decoding, telemetry and the AI-based diagnostics all depend on firmware the user installs. The hardware provides resources for all of those things, but the board as delivered has no application firmware that does them.
BeagleBoard.org says it provides editable KiCad designs, firmware sources and hardware manuals. The project is open, but the motor-control stack is part of the work the buyer takes on.
What It Means for Makers
Who it's for: embedded developers, robotics groups and drone tinkerers who want to see and modify the whole motor-control path, from schematic to commutation code. BeagleBoard.org itself suggests coordinated robot drives, multi-motor mechanisms and drone propulsion, and studying the relationship between switching waveforms, current measurements and motor torque. Typical users would be people writing their own FOC loops, experimenting with on-MCU inference for fault detection, or teaching motor control with hardware they can inspect down to the gate driver. The four-in-one layout and the flight-controller interface clearly target multirotor stacks, while the CAN transceiver on the Torque module suits CAN-connected controllers.
What it enables: the QuadESC offers editable KiCad files, published firmware sources and an MCU with a trig math unit and a neural-network accelerator. That is a platform for building an ESC, not a drop-in replacement for one. If you want a board you can bolt on and fly today, this is not it yet. It has no motor firmware installed, and its current figures are unvalidated targets with no burst duration specified.
Things to watch: thermal validation data for the 40 A / 70 A targets, a defined burst duration, a reference firmware release, and the AM13E23019 moving from PREVIEW to production status on TI's side.
Price and availability: the BeagleBoard.org product pages we read listed no price or ship date for the QuadESC or the Torque module, and LinuxGizmos states that pricing and commercial availability have not yet been announced. On those sources the board is announced with a product page. We found no evidence that it is on pre-order or shipping. We will update when BeagleBoard.org publishes pricing.
