Pyboard D-series Wireless Micropython Boards Launched for $56 and Up

buy pyboard d-series

We’ve already mentioned the latest Pyboard D-series board at the beginning of February after it was introduced at FOSDEM 2019. The board comes with a powerful STM32F7 Arm Cortex-M7 microcontroller, as well as a WiFi and Bluetooth wireless module. The news is that the board has now launched for £43.80 in.c VAT ($56) and up. A better price comparison with other boards is normally achieved by comparing the ex. VAT price of £36.50 or about $48. That may still feel a bit pricey to some, but there was enough interest to snatch all available “PYBD-SF2-W4F2” boards, and this specific board is out of stock at the time of writing. However, there are multiple variants of the board and PYBD-SF3-W4F2 is still in stock for £58.20 inc. VAT (~$76.5). We’ve now got the full Pyboard D-series “PYBD-SF2-W4F2” specifications: MCU – STMicro STM32F722IEK Arm Cortex M7 microcontroller at 216 MHz with 256KB RAM, 512KB flash, single precision FPU Storage micro SD card …

FOSSASIA 2019 Schedule – March 14-17

FOSSASIA 2019 Schedule

As its name implies, FOSSASIA is a Free and Open Source Software  event taking place every year in Asia, more specifically in Singapore. I first discovered it last year, and published a virtual FOSSASIA 2018 schedule last year to give an idea about the subjects discussed at the event. It turns out FOSSASIA 2019 is coming really soon, as in tomorrow, so I’m a bit late, but I’ll still had a look at the schedule and made my own for the 4-day event.  Thursday – March 14, 2019 10:05 – 10:25 – For Your Eyes Only: Betrusted & the Case for Trusted I/O by Bunnie Huang, CTO Chibitronics Security vulnerabilities are almost a fact of life. This is why system vendors are increasingly relying on physically separate chips to handle sensitive data. Unfortunately, private keys are not the same as your private matters. Exploits on your local device still have the potential to grant bad actors access to your screen …

$30 Arch Mix Development Board Features NXP i.MX RT1052 Crossover Processor

Arch Mix

NXP i.MX RT Arm Cortex-M7 crossover processors are supposed to fill the gap between microcontrollers and more powerful application processors thanks to real-time capabilities, and a higher CPU frequency. We’ve already covered several i.MX RT1050 series platforms including NXP’s own evaluation board and Forlinx OK1052-C development kit comprised of a carrier board and an i.MX RT1052 system-on-module. But if you’d like to experiment with NXP i.MX RT processor using a cheaper, smaller, and easier to purchase development platform, Seeed Studio has started to sell Arch Mix development board for $29.90 plus shipping. Arch Mix board specifications: SoC – NXP i.MX RT1052 Arm Cortex-M7 processor @ up to 528MHz System Memory – 32MB SDRAM Storage – 64MB Hyperflash, 8MN QSPI flash, microSD card socket Display I/F – RGB LCD interface USB – 1x micro USB 2.0 host port, 1x USB OTG port for data and power Expansion Headers – 2x 22-pin headers (2.54mm pitch) with RMII, CAN, I2C, UART, CSI, I2S, …

Pyboard D Series MicroPython Board Features STM32F7 MCU, WiFi and Bluetooth

Pyboard D Series

Micropython is a lightweight implementation of Python for microcontroller which we covered first in 2013. The port is supported by various hardware platforms, and I even tested Micropython on ESP32 a little while ago, but the developer – Damien George – also launched officially supported boards starting with Pyboard in 2014 with an STM32F4 microcontroller. At FOSDEM 2019, the upcoming Pyboard D-series (aka Pyboard D, or just PyBD) board was introduced during the Micropython presentation with a faster STM32F7 Cortex-M7 MCU, as well as built-in WiFi and Bluetooth connectivity. Pyboard D preliminary specifications: MCU – STMicro STM32F7xx Arm Cortex M7 microcontroller at 216 MHz with 512KB RAM, 2MB flash Storage – micro SD card slot, and 2x external flash chips Connectivity – WiFi & Bluetooth with on-board antenna and u.FL antenna connector USB – 1x micro USB port for power, flash disk access, and USB to serial debugging/programming Expansion 2.54mm pitch through holes for 16x GPIOs 1.27mm pitch castellated and …
