[新聞] Raspberry Pi Pico 出來了!


影片來源:Meet Raspberry Silicon: Raspberry Pi Pico now on sale at $4

Raspberry Pi 基金會 設計的第一款單晶片(microcontroller)等級的開發板 Pico 出來了!


圖片來源:Raspberry Pi Pico – what did you think?

截至 2020 年底,Raspberry Pi 已經銷售了三千七百萬台,並且被廣泛應用在個人創客、學校教學或是量產品上。但如果是想做單純 I/O 功能的應用,就需要考慮使用樹莓派的限制了。因為 Raspberry Pi 的功耗至少是 100 毫瓦(milliwatts)起跳,而且 Raspberry Pi(包括 Zero 系列)都沒有支援類比輸入,而使用 Linux 作業系統更不適合低延遲的場景。

因此 RP2040 微控制器的設計目標就是在高性能與更多靈活的 I/O 上。使用雙核 Arm Cortex-M0+ @ 133MHz 讓 RP2040 有極佳的效能,而 Mark Owen(Qfplib 函式庫作者)更優化了 Cortex-M0+ 的浮點函數,甚至比 GCC 函式庫還要快的多。雙核和大記憶體也讓 RP2040 可以執行 TensorFlow Lite 的框架,例如 Pete Warden 為 Pico 寫了一個應用

RP2040 的產品代號可以由這張圖來說明,未來將可看到 RP 開頭的微控制器系列。

而高達 26 支 multifunction 的 GPIO 腳位(3.3V 準位),具備有 ADC x2、UART x2、SPI x2、I2C x2、PWM x16,可以更靈活的控制硬體。並且可使用 C 或是 MicroPython 作為開發的程式語言。


圖片來源:Raspberry Pi Pico Review: ‘Pi Silicon’ Debuts on $4 Microcontroller

Pico 的誕生,會分食 Arduino 的市場,學校或是企業將轉投入開發 Pico 的應用。特別的是,RP2040 是使用台積電(TSMC)的 40nm 製程,相信這品質是不容懷疑。

不過 Pico 還是有些小小缺點,例如沒有內建無線功能(WiFi 和藍牙都沒有)就只能做 IoT 場景的終端節點,因此未來和 Raspberry Pi 整合搭配將會是主要應用。

[產品] PiJuice HAT – A Portable Power Platform For Every Raspberry Pi 樹莓派電源擴充板

PiJuice-HAT-4in1

 

As one of the smallest systems around there are so many amazing things you could do with the Raspberry Pi if it was self-powered and portable. Introducing PiJuice! A fully uninterruptible power supply that will always keep your Raspberry Pi powered.

Our revolutionary PiAnywhere technology contained in every PiJuice HAT – is the best way to take your Pi off the grid! The real time clock (RTC) on board will let your Pi know what time it is even with no power input or internet connection. Alongside this is an integrated microcontroller (MCU) chip which will manage soft shut down functionality and a true low power deep sleep state and intelligent startup.

You will be able to always keep track of the charge levels and other info with the two built-in tri-coloured RGB LEDs, trigger events and scripts with the three programmable buttons and since the PiJuice will use up to just five of your GPIO pins (just power and I2C), the rest are free to diversify your project. The stacking header allows you to continue to use your existing HATs and add-ons with PiJuice.
