Raspberry Pi日前針對歐洲地區(qū)推出一款僅信用卡般大小的 Model A 計算機，售價約為25美元。 Model A 是先前已上市一段時間的 Model B Raspberry Pi 的精簡版，配備了一個 USB 埠以及256MB的 RAM ，但沒有以太網(wǎng)絡(luò)連接。
精簡版的 Model A 意味著成本可較 Model B 更低10美元，而且對于一些用戶來說可能還更具有吸引力，因為它的功耗只有 Model B 的三分之一。
因此，對于電池或以太陽能供電的應(yīng)用，如機器人、遍遠(yuǎn)地區(qū)的傳感器平臺、工業(yè)自動化、數(shù)據(jù)記錄等， Model A 可說是更理想的選擇。此外，開發(fā)人員也討論透過重新編寫軟件以進一步降低功耗的可能性，或許可將使電流降低到目前的十分之一。
根據(jù) Raspberry Pi 網(wǎng)站，歐洲以外的客戶可經(jīng)由線上訂購 Model A Raspberry Pi 產(chǎn)品，但訂單處理作業(yè)可能耽擱些產(chǎn)品交貨時間。
Raspberry Pi Model A單板計算機由于少了以太網(wǎng)絡(luò)PHY，也就沒有RJ45連接器，但提供單一USB連接。

Raspberry Pi goes low power
Peter Clarke
LONDON – The Model A version of the credit-card sized Raspberry Pi computer is becoming available in Europe for a price of about $25.
The Model A is a stripped-down version of the Model B Raspberry Pi, which has been on sale for some time, but with no Ethernet, a single USB port and 256-Mbytes of RAM.
Stripping down the Model A means it is $10 lower cost than the Model B but perhaps more interestingly for some users is that it consumes about one-third of the power of the Model B. So for battery- or solar-powered applications, such as robots, sensor platforms in remote locations, industrial automation, datalogging and so on the Model A is a better option. There is discussion of rewriting software to reduce power consumpion yet further to perhaps a tenth of the current level on the Model B board.
Customers outside Europe can order a Model A Raspberry Pi, but there will be a short delay in processing their order waiting on some paperwork, according to the Raspberry Pi website.
Raspberry Pi Model A single board computer. Note the absence of Ethernet PHY, no RJ45 connector and the single USB connection.
