Specifications and operating details
The following points were extracted from the PDF text. Check the associated conditions, notes and limits in the complete document before using a value in a design.
- CAN Specification 2.0) Integrated Components on Module 40 MHz crystal oscillator Antenna Options ESP32-MINI-1: On-board PCB antenna ESP32-MINI-1U: external antenna via a connector Operating Conditions Operating voltage/Power supply: 3.0~ 3.
- Both ESP32-MINI-1 and ESP32-MINI-1U come in two versions: 85 °C version 105 °C version The two versions only vary in maximum ambient temperature.
- The flash supports: - More than 100,000 program/erase cycles - More than 20 years data retention time At the core of this module is ESP32-U4WDH, an Xtensa 32-bit LX6 CPU that operates at up to 240 MHz.
- MTDI is used to select the VDD_SDIO power supply voltage at reset: MTDI = 0 (by default), VDD_SDIO pin is powered directly from VDD3P3_RTC.
- MTDI = 1, VDD_SDIO pin is powered from internal 1.8 V LDO.
- This functionality can be overridden by setting EFUSE_SDIO_FORCE to 1, in which case the EFUSE_SDIO_TIEH determines the VDD_SDIO voltage: EFUSE_SDIO_TIEH = 0, VDD_SDIO connects to 1.8 V LDO.
- Feature List Two I2C controllers: one in the main system and one in the low-power system Standard mode (100 Kbit/s) Fast mode (400 Kbit/s) Espressif Systems 18 Submit Documentation Feedback ESP32-MINI-1 & MINI-1U Datasheet v1.5 Up to 5 MHz.

- Revision History
Engineering review checklist
- Confirm supply rails, clock limits, memory size, peripheral mapping and I/O voltage compatibility.
- Check package pinout, boot configuration, programming interface and silicon-revision errata.
- Budget decoupling, thermal margin, startup timing and firmware recovery behavior before release.
Always confirm values against the latest manufacturer-controlled datasheet, especially when qualifying a substitute or releasing a production BOM.
