EsPiFF board combines ESP32 module with RP2040 MCU in the Raspberry Pi 4 form factor (Crowdfunding)

The EsPiFF board may look like a Raspberry Pi 4 Linux SBC but it is equipped with an ESP32-WROVER WiFi and Bluetooth module together with a Raspberry Pi RP2040 microcontroller that acts as a co-processor. The goal here is to provide a Raspberry Pi 4 replacement for applications that require higher reliability and even 24/7 operation without necessarily needing the processing power and multimedia capabilities of the Broadcom BCM2711 Arm processor found in the Pi or the versatility of a Linux operating system. EsPiFF board specifications: Wireless module – ESP32-WROVER module with dual-core ESP32-D0WDQ6 microcontroller with 2.4 GHz WiFi 4 and Bluetooth, 8 MB PSRAM and 16 MB flash Co-processor – Raspberry Pi RP2040 dual-core Cortex-M0+ microcontroller @ up to 133 MHz with 16MB flash used to emulate the Raspberry Pi’s GPIOs on the 40-pin header Additional storage 2 KB of fast FRAM for permanent storage of process data.

Air32F103 is a clone of STM32F103 clocked at up to 216 MHz

Air32F103 is yet another clone of the STM32F103 microcontroller that can be faster if needed with a clock of up to 216 MHz instead of 72 MHz for the original STMicro STM32 Arm Cortex-M3 microcontroller. The first SKU of the family is the Air32F103CBT6 whose peripherals and hardware design are compatible with equivalent STM32F103CBT6 parts and offered with 32KB RAM and 128KB flash. There’s also a Bluepill-like development board, but with a different pinout, made by LuatOS. Documentation for the board and microcontroller can be found in a Wiki including the MCU datasheet that indicates models with 256KB flash and 64KB SRAM (Air32F103CCT6) and 96KB SRAM (Air32F103RPT6). Since the wiki is in Chinese only, you may want to head over a post in English on Chowdera to learn how to get started with the Keil IDE using code hosted on Gitee. The chip and board were also spotted on EEVBlog […]
