Banana Pi Leaf ESP32 S3 Series of Low-Powered Microcontrollers Designed for

Banana Pi Leaf ESP32 S3

low-powered microcontrollers designed for IoT development

Product Descrtion:

It supports 2.4 GHz Wi-Fi and Bluetooth® LE dual-mode wirele communication, the perheral is compatible with low-power hardware design, and the power consumption is only 10uA in deep sleep mode.

The main controller supports two power supply inputs: USB and external 3.7V lithium battery, both can be interchangable freely. The battery could also be charged while USB is plugged in. Compact size, various interface, easy to use, and can be directly applied to low-power IoT projects.

In terms of programming, the Leaf-S3 supports ESP-IDF, , micropython and other methods.

The IO pins on BPI-Leaf-S3 are identical to the Espreif ESP32-S3-DevKitC-1, developers can add perherals that are supported by DevKitC-1 onto the BPI-Leaf-S3, and can also combine it onto a breadboard.

Espreif ESP32-S3 :

Wi-Fi + Bluetooth 5 (LE) Wirele Connectivity: ESP32-S3 supports a 2.4 GHz Wi-Fi (802.11 b/g/n) with 40 MHz of bandwidth support. The Bluetooth Low Energy subsystem supports long range through Coded PHY and advertisement extension. It also supports higher transmiion speed and data throughput, with 2 Mbps PHY. Both Wi-Fi and BLE have superior RF performance that is maintained even at high temperatures.

AI Acceleration Support: ESP32-S3 has additional support for vector instructions in the MCU, which provides acceleration for neural network computing and signal proceing workloads. The software libraries for the above-mentioned optimized functions will become available very soon, in the form of updates to ESP-WHO and ESP-Skainet.

Rich Set of IO Perherals: ESP32-S3 has 44 programmable GPIOs, namely 10 more GPIOs than those of ESP32. ESP32-S3 supports all the commonly-used perherals, such as SPI, I2S, I2C, PWM, RMT, ADC and UART, SD/MMC host and TWAITM. In total, 14 GPIOs can be configured as capacitive touch input for HMI applications. Apart from all these perherals, however, ESP32-S3 is also equped with an ultra-low-power (ULP) core that supports multle low-power modes in a variety of such use-cases.

Security:ESP32-S3 provides all the neceary security requirements for building securely connected devices, without requiring any external components. It supports AES-XTS-based flash encryption and RSA-based secure boot. In addition, ESP32-S3 has a digital signature perheral and an HMAC module, which provide functionality that is similar to the hardware secure element, thus protecting the private or symmetric key from software attacks and identity theft. ESP32-S3 also has a “World Controller” perheral that provides two fully-isolated execution environments, which enable the implementation of a trusted-execution environment or a privilege-separation scheme.

What follows is a descrtion of the most ant features of ESP32-S3.

ESP32-S3 is a dual-core XTensa LX7 MCU, capable of running at 240 MHz. Apart from its 512 KB of internal SRAM, it also comes with integrated 2.4 GHz, 802.11 b/g/n Wi-Fi and Bluetooth 5 (LE) connectivity that provides long-range support. It has 45 programmable GPIOs and supports a rich set of perherals. Compared with ESP32, it supports larger, high-speed octal SPI flash, and PSRAM with configurable data and instruction cache.
