UNIT ELECTRONICS DualMCU Product Reference Manual

Product Reference Manual (V1.2)
Description
Unit DualMCU brings the Raspberry Pi
RP2040 microcontroller
ESP32 WROOM chip in a simple one
module, make the most of the dual core
32-bit Arm® Cortex®-M0+ to make Internet
of Things projects with Bluetooth® and
Wi-Fi connectivity.
DualMCU has been thought of as a mix
between two 32-bit microprocessors: a
Raspberry RP2040 cortex M0+ running at
133 Mhz and an Espressif ESP32 running
up to 240 MHz, in this way we implement all
the power of both microcontrollers in a
single development card. With a PCB size
of 36mm x 84mm and using surface mount
technology, four programmable cores with
wireless functions and features are found
with very low power consumption.
Both microcontrollers can communicate
via serial protocol by simply activating a
2-way DIP SWITCH, for example, we can
program the ESP32
co-processor to provide
microcontroller with WIFI or BLUETOOTH
communication. For programming, there is a
mechanical selector that allows us to select
which MCU connects using a single USB type
C connector.
Interconnect a large number of I2C
devices using its STEMMA, QWIIC and
GROVE compatible JST-SH I2C connectors
and dive into real-world projects with the
onboard RGB 2020 and WS2812B LED.

Unit Electronics ® DualMCU RP2040+ESP32
With over 46 general purpose pins
(GPIO), DualMCU exposes most output
ports of both microcontrollers via pin
headers and JST-SH
(STEMMA, QWIIC
compatible). It has
peripherals such as: UART, I2C, SPI, PWM,
ADC, Touch and state machines. The
multiple forms of connection to sensors,
actuators or even
microcontrollers will only be limited by your
creativity.
