Technical Details & Description

The ESP32-C3-MINI-1U-H4 is a surface-mount Wi-Fi + BLE combo module from the ESP32-C3 series, built around the ESP32-C3FH4 chip. It packs 4MB flash, 384kB ROM, and 408kB SRAM. RF covers 2.412 GHz to 2.484 GHz for 802.11b/g/n at up to 150 Mbps, plus Bluetooth v5.0. The module does not include an onboard antenna — it uses an I-PEX connector for an external antenna, which gives you control over the RF path and antenna gain.

Key RF and power ratings

Transmit power is 20.5 dBm. Receive sensitivity is -104 dBm. Current draw during transmit runs 290 mA to 350 mA; receiving pulls 82 mA to 84 mA. Budget the 3.3 V rail for the peak TX current plus margin — a 500 mA LDO is a safe choice.

Serial interfaces and debug access

JTAG is available for debug — no separate debug adapter needed if you bring out the JTAG pins.

The module is surface-mount.

Frequently asked questions

Does ESP32-C3-MINI-1U-H4 include an antenna?

No — the module has an I-PEX connector for an external antenna. You supply the antenna element and cable.

What is the flash memory size of ESP32-C3-MINI-1U-H4?

4 MB flash, plus 384 kB ROM and 408 kB SRAM.
