LORDWORLD ESP32-H2 Mini Development Board ESP32-H2FH4S 4MB Flash pre-soldered Header

SKU CH-YRXA-2WHH2

Compact IoT board with RISC-V core, 4 MB flash and BLE 5, Zigbee 3.0 and Thread radios, pre-soldered header and Type-C power

  • RISC-V 32-bit single-core processor runs up to 96MHz for responsive edge computing
  • Integrated BLE 5 and IEEE 802.15.4 radio supports Zigbee 3.0 and Thread mesh networking
  • 4MB Flash built into the ESP32-H2FH4S chip stores firmware and data locally
  • USB Type-C connector simplifies power and serial debugging
  • Castellated edges allow direct soldering onto custom carrier boards

Compact RISC-V Board for Low-Power Mesh Nodes

This LORDWORLD development board integrates an ESP32-H2FH4S chip with a 32-bit single-core RISC-V processor running at up to 96 MHz and 4 MB of flash. It targets engineers building Thread, Zigbee 3.0 or BLE 5 mesh devices that need a small castellated footprint. The pre-soldered header lets hobbyists prototype immediately without surface-mount equipment.

Fits Breadboards and Carrier Boards Alike

A USB Type-C port supplies power and a serial console while exposing the MCU's peripheral set for sensors or actuators. Castellated edges allow the module to be reflow-soldered onto a custom carrier once the prototype is validated. No on-board antenna tuning or external RF components are required because the chip integrates the radio front-end.

Steady Throughput in Dense 802.15.4 Networks

The IEEE 802.15.4 radio maintains reliable Zigbee and Thread connectivity even when many nodes share the same channel. Duty-cycled firmware keeps average current draw low during long-term deployments. Thermal output remains negligible so no heatsink or forced airflow is needed inside sealed enclosures.

Questions about this item

What is the maximum processor frequency before thermal limits appear?

The RISC-V single-core processor runs at up to 96 MHz, and sustained workloads at this frequency will hit thermal limits first.

How much current does the board draw when the radio runs BLE 5 and IEEE 802.15.4 continuously?

Continuous dual-protocol radio operation draws noticeable current from the Type-C supply, so expect warm operation and plan for adequate USB power.

Which host interface must my computer provide to program and power the board?

A USB Type-C port is required for both power and serial programming access.
