Two small green ESP32-H2 mini development boards with USB-C connectors and castellated edges

LORDWORLD

LORDWORLD ESP32-H2 Mini Development Board 2 Pack 4MB Flash 96MHz RISC-V 32-bit

SKU CH-YJCJ-ZAMGP

Two development boards with RISC-V 32-bit processors running at 96MHz, 4MB flash, and BLE 5 plus IEEE 802.15.4 for Zigbee 3.0 and Thread connectivity

  • RISC-V 32-bit single-core processor up to 96MHz
  • 4MB flash memory for firmware and data storage
  • BLE 5 and IEEE 802.15.4 support for Zigbee 3.0 and Thread
  • USB Type-C connector for power and programming
  • Castellated edges enable direct soldering to carrier boards

ESP32-H2 Mini Development Board 2 Pack

The LORDWORLD ESP32-H2 Mini Development Board comes as a two-pack of compact IoT edge devices built around the ESP32-H2FH4S chip. Each board features a RISC-V 32-bit single-core processor running up to 96MHz with 4MB of integrated flash memory. They target makers and engineers developing Thread, Zigbee 3.0 or BLE 5 connected devices who need a ready-to-code platform with pre-soldered headers.

Pre-soldered headers and castellated edges

Pre-soldered pin headers let you plug the boards straight into a breadboard or custom carrier without any iron work. The castellated module edges also allow direct surface-mount soldering onto a final PCB when the prototype moves to production. A USB Type-C connector supplies power and a serial console, so no separate FTDI adapter is required during bring-up.

4MB flash and 96MHz headroom

The 4MB flash holds the application firmware, protocol stacks and any OTA update partitions for Thread or Zigbee 3.0 networks. The 96MHz RISC-V core handles typical sensor polling, mesh routing and BLE 5 advertising with cycles to spare. Heavy cryptographic workloads or large local data logging will exhaust the available flash and CPU budget, so designs needing megabytes of local storage or sustained high-throughput encryption should plan external memory.

Questions about this item

Will the ESP32-H2FH4S chip or the castellated module need replacement after extended use?

The board uses a soldered ESP32-H2FH4S chip and castellated edges for direct carrier-board mounting; neither is designed as a user-replaceable part.

What limits sustained throughput on the IEEE 802.15.4 radio?

The single-core RISC-V processor at 96 MHz and the shared 4 MB flash set the practical ceiling for continuous Zigbee 3.0 or Thread traffic.

How much heat does the board produce when the radio runs all day?

With a 96 MHz RISC-V core and integrated BLE 5 plus IEEE 802.15.4 radios, the mini board stays cool enough for enclosed projects without active cooling.
