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

AIR32F103 development board

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 […]

Starfish PnP machine control board combines Raspberry Pi RP2040 MCU with TMC2209 motor drivers

StarFish Raspberry Pi RP2040 PnP control board

We’ve already seen the Raspberry Pi RP2040 MCU in a 3D printer controller board, so it should come as no surprise that the dual-core microcontroller also found its way into a Pick-and-Place (PnP) machine control board. Designed by Thea Flowers, the Starfish board leverages the RP2040 MCU capabilities to control three Trinamic TMC2209 motor drivers, MOSFET drivers to control DC vacuum pumps, two vacuum sensors, and offer RS485 and I2C connectivity for feeders and peripherals respectively. Starfish specifications: MCU – Raspberry Pi RP2040 dual-core Cortex M0+ microcontroller at up to 133 MHz with 264 kB of embedded SRAM Storage – QSPI flash Motor drivers – 3x TMC2209 drivers for X, Y1, and Y2 MOSFETs – 2x MOSFETs to control the 2x vacuum pumps Valve drivers – 2x TI DRV120 single-channel relay, solenoid, and valve drivers to control two pneumatic solenoid valves Sensors – 2x CFSensor XGZP6857D I2C pressure sensor modules […]
