1 Module Overview
1.2 Description
ESP32-PICO-MINI-02 and ESP32-PICO-MINI-02U are two general-purpose Wi-Fi + Bluetooth + Bluetooth LE
MCU modules. They are based on ESP32-PICO-V3-02, a System-in-Package (SiP) device, which integrates an 8
MB SPI flash, 2 MB SPI Pseudo static RAM (PSRAM) and 40 MHz crystal oscillator. The rich set of peripherals
and a small size make the two modules an ideal choice for a wide variety of IoT applications, ranging from home
automation, smart building, consumer electronics to industrial control, and they are suitable for intelligent
speakers, speech recognition toys, intelligent gateway and Ethernet, etc.
ESP32-PICO-MINI-02 comes with a PCB antenna. ESP32-PICO-MINI-02U comes with a connector for an
external antenna. The ordering information of the two modules is listed as follows:

At the core of ESP32-PICO-MINI-02 and ESP32-PICO-MINI-02U is the ESP32-PICO-V3-02 sip*. The chip
embedded is designed to be scalable and adaptive. There are two CPU cores that can be individually controlled,
and the CPU clock frequency is adjustable from 80 MHz to 240 MHz. The chip also has a low-power
coprocessor that can be used instead of the CPU to save power while performing tasks that do not require much
computing power, such as monitoring of peripherals. This ESP32 chip integrates a rich set of peripherals,
ranging from SD card interface, capacitive touch sensors, ADC, DAC, Two-Wire Automotive Interface, to
Ethernet, high-speed SPI, UART, I2S, I2C, etc.
Note:
* For details on the part numbers of the ESP32 family of chips, please refer to the document ESP32 Series Datasheet.

3.3 Strapping Pins
Note:
The content below is excerpted from Section Strapping Pins in ESP32 Series Datasheet. For the strapping pin mapping
between the chip and modules, please refer to Chapter 5 Module Schematics.
ESP32-PICO-V3-02 has five strapping pins:
• MTDI
• GPIO0
• GPIO2
• MTDO
Espressif Systems
11
ESP32-PICO-MINI-02 & PICO-MINI-02U Datasheet v1.1
Submit Documentation Feedback
3 Pin Definitions
• GPIO5
Software can read the values of these five bits from register ”GPIO_STRAPPING”.
During the chip’s system reset release (power-on-reset, RTC watchdog reset and brownout reset), the latches of
the strapping pins sample the voltage level as strapping bits of ”0” or ”1”, and hold these bits until the chip is
powered down or shut down. The strapping bits configure the device’s boot mode, the operating voltage of
VDD_SDIO and other initial system settings.
Each strapping pin is connected to its internal pull-up/pull-down during the chip reset. Consequently, if a
strapping pin is unconnected or the connected external circuit is high-impedance, the internal weak
pull-up/pull-down will determine the default input level of the strapping pins.
To change the strapping bit values, users can apply the external pull-down/pull-up resistances, or use the host
MCU’s GPIOs to control the voltage level of these pins when powering on ESP32-PICO-V3-02.
After reset release, the strapping pins work as normal-function pins.
Refer to Table 3 for a detailed boot-mode configuration by strapping pins.

The module integrates a 3.3 V SPI flash, so the pin MTDI cannot be set to 1 when
the module is powered up.

for a particular power domain of pins.

For VDD3P3_CPU and VDD3P3_RTC power domain, per-pin current sourced in the same domain is
gradually reduced from around 40 mA to around 29 mA, VOH >=2.64 V, as the number of currentsource pins increases.

Pins occupied by flash and/or PSRAM in the VDD_SDIO power domain were excluded from the test.
4.4 Current Consumption Characteristics
Owing to the use of advanced power-management technologies, the module can switch between different power
modes. For details on different power modes, please refer to Section RTC and Low-Power Management

The current consumption measurements are taken with a 3.3 V supply at 25 °C of ambient
temperature at the RF port. All transmitters’ measurements are based on a 100% duty cycle.
2
The current consumption figures for in RX mode are for cases when the peripherals are disabled and the CPU idle.

The current consumption figures in Modem-sleep mode are for cases where the CPU is powered on and the
cache idle.
2
When Wi-Fi is enabled, the chip switches between Active and Modem-sleep modes. Therefore, current
consumption changes accordingly.
3
In Modem-sleep mode, the CPU frequency changes automatically. The frequency depends on the CPU load
and the peripherals used.
4
During Deep-sleep, when the ULP coprocessor is powered on, peripherals such as GPIO and RTC I2C are
able to operate.
5
The ”ULP sensor-monitored pattern” refers to the mode where the ULP coprocessor or the sensor works
periodically. When ADC works with a duty cycle of 1%, the typical current consumption is 100 µA.

Device should operate in the center frequency range allocated by regional regulatory authorities.
Target center frequency range is configurable by software.
2
For the modules that use external antennas, the output impedance is 50 Ω. For other modules
without external antennas, the output impedance is irrelevant.
4.5.2 Transmitter Characteristics
Target TX power is configurable based on device or certification requirements. The default characteristics are
provided in Table 10.

There are a total of eight power levels from 0 to 7, and the transmit power ranges from –12 dBm to 9
dBm. When the power level rises by 1, the transmit power increases by 3 dB. Power level 4 is used by
default and the corresponding transmit power is 0 dBm.

Note:
• Soldering Pad 49 to the Ground of the base board is not necessary for a satisfactory thermal performance. If users
do want to solder it, they need to ensure that the correct quantity of soldering paste is applied.
• To ensure that the power supply to the ESP32 chip is stable during power-up, it is advised to add an RC delay
circuit at the EN pin. The recommended setting for the RC delay circuit is usually R = 10 kΩ and C = 1 µF. However,
specific parameters should be adjusted based on the power-up timing of the module and the power-up and reset
sequence timing of the chip. For ESP32’s power-up and reset sequence timing diagram, please refer to Section
Power Scheme in ESP32 Series Datasheet.

8 Product Handling
8.1 Storage Conditions
The products sealed in moisture barrier bags (MBB) should be stored in a non-condensing atmospheric
environment of < 40 °C and 90%RH. The module is rated at the moisture sensitivity level (MSL) of 3.
After unpacking, the module must be soldered within 168 hours with the factory conditions 25 ± 5 °C and 60
%RH. If the above conditions are not met, the module needs to be baked.
8.2 Electrostatic Discharge (ESD)
