Three small green circuit boards with USB-C connectors and pin headers

LORDWORLD

LORDWORLD ESP32-H2 Mini Development Board 3-pack 4MB Flash

SKU CH-VZWP-3V77Q

Three ESP32-H2 boards with RISC-V processor, 4MB flash, BLE 5 and Zigbee 3.0/Thread radios, USB-C and castellated edges for direct soldering

  • RISC-V 32-bit single-core processor running up to 96 MHz
  • 4 MB flash memory stores firmware and application data
  • BLE 5 plus IEEE 802.15.4 radio supports Zigbee 3.0 and Thread
  • USB Type-C connector simplifies power and programming
  • Castellated edges enable direct soldering onto custom carrier boards

Three-Unit Pack for Mesh Prototyping

This pack contains three LORDWORLD ESP32-H2 Mini development boards, each built around the ESP32-H2FH4S chip with a 32-bit RISC-V core running up to 96MHz and 4MB of flash. They expose a USB-C connector and castellated edges for direct soldering, making them suited to engineers building Thread or Zigbee 3.0 mesh networks.

Targets Multi-Node Wireless Developers

Ideal for developers who need multiple identical nodes to test BLE 5, IEEE 802.15.4 or Thread routing in a single bench setup. Not suitable for buyers who require Wi-Fi connectivity, higher compute throughput or a different instruction-set architecture.

RISC-V Core Defines Toolchain Choice

The single-core 32-bit RISC-V processor at up to 96MHz determines the compiler, SDK and debug toolchain you must use; code written for Xtensa-based ESP32 variants will not run on this hardware.

Highlights

  • RISC-V 32-bit single-core processor running up to 96 MHz
  • 4 MB flash memory stores firmware and application data
  • BLE 5 plus IEEE 802.15.4 radio supports Zigbee 3.0 and Thread
  • USB Type-C connector simplifies power and programming
  • Castellated edges enable direct soldering onto custom carrier boards

Questions about this item

What wireless standard limits the data rate of the IEEE 802.15.4 radio?

The board uses IEEE 802.15.4 for Zigbee 3.0 and Thread, which defines the physical-layer rate for those protocols.

What board spacing do the castellated edges require for direct soldering?

The castellated module is designed to be soldered directly onto a carrier board with matching pad pitch.

Which step is often missed when flashing firmware over the Type-C connector?

Hold the BOOT button while pressing RESET to enter download mode before starting the flash tool.
