STMicro STM32WL is the World’s First LoRa SoC

There is no denying that the Internet of Things is going to disrupt a lot of markets and it’s already happening to some extent. The question being asked is: “What IoT connectivity technology will lead this disruption era?”. One major technology in this connectivity race is LoRa. LoRa’s long-range, low-power, small footprint, simplicity, and the amazing community backing it, have allowed it to find its way into various applications while gaining for the top LPWAN IoT connectivity technology. STMicroelectronics, one of the biggest semiconductor manufacturer, also believes in the potential of LoRa with the launch of STM32WL, making it the World’s first die-integrated LoRa System-on-Chip. Traditional LoRa embedded platforms usually involve the need for a separate MCU chip and different LoRa transceiver chips either coupled together in one single package or separately. This undoubtedly adds extra design complexity, size, and even cost. STMicro hopes to address this with their STM32WL SoC. This new device opens the door to original applications by …

MYIR Launches SoM & Development Board based on STM32MP1 Microprocessor

MYIR, the Chinese based company that has developed several ARM-based hardware solutions, has introduced a new SoM powered by the ST’s STM32MP1 microprocessor called the MYC-YA157C CPU Module with an accompanying development board known as the MYD-YA157C development board. Early last year, STMicro announced the introduction of the STM32MP1, the first STM32 MPU (Microprocessor Unit) that features one or two Arm Cortex-A7 cores running Linux, as well as an Arm Cortex-M4 real-time core making it possible to use previous STM32 codes on the new unit. Although, less than 1-year-old, the STM32MP1 microprocessor has since be deployed on a couple of development boards like the STMicro’s own discovery kits and evaluation platform, Emtrion emSBC-Argon, PanGu single-board computer, and even octavo systems unveiled the OSD32MP15x system-in-package. One primary observation with these other developments boards is their relatively steep cost, and something MYIR aims to address. MYiR MYC-YA157C STM32MP1 CPU Module The MYC-YA157C CPU Module is a cost-effective STM32MP1 SoM that features the …

$3 STM32 “Black Pill” Board Features STM32F4 Cortex-M4 MCU, Optional SPI Flash

Blue Pill 2 Cortex-M4 MCU

STM32 “Blue Pill” is a popular, and cheap (>$2) development board based on STMicro STM32F103C8T6 Arm Cortex-M3 microcontroller and programmable with the Arduino IDE. I’ve just been informed the board got an upgrade of sorts with a “Blue Pill 2” board featuring either STM32F401CCU6 or STM32F411CEU6 Arm Cortex-M4F microcontroller, and a USB Type-C port for power and programming. It’s black, so instead, I’ll call Black Bill as some others appear to do. Specifications for the Blue Pill & Black Pill boards (new features in bold): MCU (one of the other) STMicro STM32F103C8T6 ARM Cortex-M3 MCU @ 72 MHz with 64KB flash memory, 20KB SRAM. STMicro STM32F401CCU6 Arm Cortex-M4F MCU @ 84 MHz with 256 KB flash, 64KB SRAM STMicro STM32F411CEU6 Arm Cortex-M4F MCU @ 100 MHz with 512KB flash, 128KB SRAM Storage – Footprint for SPI flash USB Blue Pill – 1x micro USB port for power and programming Black Pill – 1x USB Type-C port for power and programming …

Fingerprint Identification with STM32 MCU and Serial TFT LCD Module

STM32 Fingerprint TFT LCD

CNXSoft: This is a guest post by Amy working for STONE Technology, a company specializing in industrial liquid crystal display modules This month, I planned to develop a fingerprint door lock project. When I selected the fingerprint identification module, the project was suspended. However, I thought that since the fingerprint identification module had been purchased, I would simply test it. This fingerprint module can be easily purchased online, connected over UART to an MCU  board. It supports fingerprint scanning, fingerprint entry, fingerprint comparison, and fingerprint deletion. Since the fingerprint module manufacturer provides a demo program for STM32F103 series microcontrollers, I bought a small development board based on STM32F103C8T6. The demo program of the fingerprint module uses LED lights to prompt the user to enter the fingerprint and compare the status (success or failure). But I want to use an LCD display, so I chose a 480×272 resolution serial LCD display. The specific model of this display is STONE STVC050WT-01, which …

ctxLink Open Hardware WiFi Debug Probe is based Black Magic Probe (Crowdfunding)

ctxlink

Last month, we wrote about Blip nRF52840 dev board that also included an STM32F103 MCU running the open source Black Magic Probe (BMP) firmware for debugging and programming. Based on the original Black Magic Probe hardware product page, BMP is a JTAG and SWD adapter used for programming and debugging ARM Cortex MCUs, and does not require intermediate programs such as OpenOCD or STLink server. Instead, you can run GNU Debugger (GDB) and select the virtual COM port offered by the debug board. The reason I’m bringing BMP again today, is because a new open source hardware wireless debugging probe for Cortex-M based on Black Magic Probe has been launched in the last few days. ctxLink key features and specifications: Microcontroller – STMicro STM32F401RE Arm Cortex -M4F MCU at up to 84 MHz Connectivity – 802.11b/g/n WiFi via Microchip WINC1500 module USB – 1x micro USB port for connection to host computer and/or power Debugging Features Implements SWD and JTAG …

STMicro Launches the first 8-pin STM32 Microcontrollers

8-pin STM32 / STM32G0

At the end of last year, STMicro introduced what they claim is the first 90nm mainstream microcontroller with STM32G0 Arm Cortex-M0+ MCU clocked at 64 MHz. At the time, the family included parts with 24, 32, 48 and 64 pins packages, but there were also plans for 8-pin and 100-pin STM32G0 microcontrollers. The company has now just announced availability for the first 8-pin STM32 microcontrollers thanks to four new STM32G0 SKUs with up to 8KB RAM and 32KB flash in an SO8N package. The 90nm process node and simpler design make the new microcontrollers most suitable for cost & energy-conscious applications governed by battery-capacity limits, eco-design legislation, or market expectations such as appliance energy ratings. 8-pin STM32 Microcontrollers Available Now STM32G030J6 is part of STM32G0 Value Line with 32KB flash and 8KB memory, as well as 6 I/O pins supporting GPIO, SPI, I2C, and UART outputs. STM32G031J6, STM32G031J4, and STM32G041J6 Access Line MCUs are also available in SO8N (6 x …
