49 cents “Black Pill” board clone features AT32 Cortex-M4F microcontroller

The “Black Pill” board with an STM32F4 Cortex-M4F MCU is already cheap, but I’ve just come across a clone going for just 49 cents plus shipping (34 cents to Thailand) based on a 240 MHz AT32 (or AT32F4) Cortex-M4F microcontroller with Arduino support. [Edit: the price looks like a lottery and everybody seems to get a different price, and not related to VAT. See comments section] Other features are pretty much the same with two 20-pin headers for GPIOs, an SWD header, a USB Type-C port for power and programming, and a few buttons. WeAct “Black Pill” board specifications: Microcontroller – Artery Technology AT32F403ACGU7 Cortex-M4F MCU @ 240MHz with 96 + 128KB RAM, 256KB zero wait-state flash, 768KB non-zero wait-state flash; note: RAM and flash size are somehow configurable by the user, and the numbers listed here are the maximum capacities. Storage – Footprint for SPI flash USB – 1x […]

Sparkfun launches cheaper no-code “DataLogger IoT” board compatible with Qwiic modules

Last May, SparkFun introduced the “Datalogger IoT – 9DoF” no-code platform with support for over 50 Qwiic sensor modules and a built-in 9-axis IMU sensor and magnetometer. Taking into consideration that some users may not make use of the built-in sensors, the company decided to launch a cheaper version called the “DataLogger IoT” that can still get data from Qwiic sensor and GPS modules without any programming thanks to the “no-code” Arduino firmware preloaded on the ESP32-WROOM-32E module. SparkFun DataLogger IoT specifications: Wireless module – ESP32-WROOM-32E with: ESP32 dual-core microcontroller 4MB flash 2.4 GHz WiFi and Bluetooth LE connectivity, built-in PCB antenna Storage – MicroSD card slot USB – 1x USB Type-C port for power and configuration via CH340C Expansion – 2x Qwicc I2C connectors for sensors and/or GPS module Misc Boot and Reset buttons Status and charging LED, WS2812 RGB LED Jumpers to enable/disable LEDs, I2C pull-up resistors, and […]
