Dual ESP32-S3 development board

This board pairs two ESP32-S3 chips with a CH343 UART controller to deliver 4 Mbps transfers at a 1000 Hz polling rate. It targets makers and engineers building low-latency input devices or edge-computing prototypes that need dual-core Wi-Fi and Bluetooth 5 connectivity. The pre-flashed Full-Pass v3 firmware provides immediate mouse-simulation capability without additional toolchain setup.

Headroom at 4 Mbps and 1000 Hz

The dual-chip architecture sustains the rated 4 Mbps link with zero-latency UART signalling, so high-frequency HID streams and real-time sensor fusion run without throttling. Workloads that exceed the 32 GPIOs or require more than two concurrent USB endpoints will hit the silicon limits, and the single UART channel cannot serve additional high-speed peripherals simultaneously.

Button-enabled shell and twin cables

A moulded shell with an integrated tactile button lets developers trigger firmware events or mode switches without soldering headers. Two double-ended USB-C cables are included, removing the need to source matching leads for power, flashing and host communication during bring-up. No extra software utilities or configuration files are bundled beyond the factory firmware image.

Questions about this item

Will the MAKCM V2 board work with my older USB 2.0 hubs and ports?

The board includes a CH343 UART controller that transfers data at 4Mbps over USB. It uses the two double-ended USB-C cables supplied, so it will connect to any USB host that accepts a USB-C plug.

How can I verify the 1000Hz polling rate is active after I flash the board?

The unit ships pre-flashed with Full-Pass v3 firmware that targets 1000Hz polling. You can confirm the rate in your operating system mouse settings or with a USB polling-rate test utility.

The listing mentions two double-ended USB-C cables and a button-enabled shell — is anything else required to start developing?

The package contains the PCB, the shell with integrated button, and the two double-ended USB-C cables. No extra cables or programmers are needed; just connect to a host PC and begin.
