Polos GD32V Alef is a Tiny RISC-V MCU Board Selling for $3

We first found out about GigaDevice GD32V 32-bit RISC-V MCU last summer, as an update/alternative to the earlier STM32 compatible GD32 Arm Cortex-M3 microcontroller from the company with higher performance and lower power consumption, while keeping the price identical. The first low-cost GD32V development board we covered was Longan Nano going for $5 with an OLED display and an acrylic case. If you don’t need either or want to access all pins from the 48-pin MCU, you can now order an even cheaper GD32V RISC-V MCU board with Polos GD32V Alef going for $2.99 on Analoglamb website. Polos GD32V Alef board specifications: MCU – Gigadevice GD32VF103CBT6 32-bit RISC-V (rv32imac) microcontroller @ 108 MHz with 128KB Flash, 32KB SRAM USB – 1x micro USB OTG port for power and programming Expansion – 52 through holes (2.54mm pitch) exposing all pins from the MCU including 3x USART, 2x I2C, 3x SPI, 2x […]

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

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 […]

Banana Pi BPI-F2S Industrial SBC Launched for $58 with Linux 4.19 based Debian or Fedora OS

Last month we covered Banana Pi BPI-F2S single board computer (SBC) for industrial, IoT, and smart audio application that was powered by the intriguing SunPlus SP7021 “Plus1” processor featuring four Cortex-A7 cores, one ARM9 ARM9 real-time core, and one 8051 I/O controller core, as well as up to 512MB built-in DDR3 RAM. At the time, the board was not available, and we had limited information about software support, except the company would provide a Yocto-based Linux distribution. The good news is that you can now buy Banana Pi BPI-F2S industrial SBC on Aliexpress for $58 and Taobao for 390 RMB, and the company released source code and OS images for the board. Here’s a reminder of Banana Pi BPI-F2S specifications: SoC – Sunplus SP7021 “Plus1” with a quad-core Cortex-A7 processor @ 1.0 GHz, one Arm A926 microprocessor, an 8051 core to handle I/Os, and 128MB or 512MB DDR3 DRAM.
