| Content | | ESP32 is a single 2.4 GHz Wi-Fi-and-Bluetooth combo chip designed with the TSMC ultra-low-power 40 nm technology. It is designed to achieve the best power and RF performance, versatility, and reliability in a wide variety of applications and power scenarios.
Ideal for low-power applications, the ESP32 SoC features fine-grained clock gating, multiple power modes, and dynamic power scaling. A low duty cycle is used to minimize the amount of energy that the ESP32 SoC expends. The output of the power amplifier is also adjustable, thus contributing to an optimal trade-off between communication range, data rate, and power consumption. The ESP32 SoC is highly-integrated with in-built antenna switches, power amplifiers, low-noise receive amplifiers, and power management modules. ESP32 adds priceless functionality and versatility to IoT applications with minimal Printed Circuit Board (PCB) requirements.

The ultra-low-power STM32L073RZT6 microcontrollers incorporate the connectivity power of the universal serial bus (USB 2.0 crystal-less) with the high-performance Arm Cortex-M0+ 32-bit RISC core operating at a 32 MHz frequency, a memory protection unit (MPU), high-speed embedded memories (up to 192 Kbytes of Flash program memory, 6 Kbytes of data EEPROM and 20 Kbytes of RAM) plus an extensive range of enhanced I/Os and peripherals.
The STM32L073RZT6 devices provide high power efficiency for a wide range of performance. It is achieved with a large choice of internal and external clock sources, an internal voltage adaptation, and several low-power modes.
The STM32L073RZT6 devices offer several analog features, one 12-bit ADC with hardware oversampling, two DACs, two ultra-low-power comparators, several timers, and one low-power timer (LPTIM), four general-purpose 16-bit timers, and two basic timers, one RTC and one SysTick which can be used as timebases. They also feature two watchdogs, one watchdog with independent clock and window capability and one window watchdog based on bus
clock.
