批發(fā)價格更優(yōu)惠
全面升級！用料更足，黑色鍍金板耐氧化，鍍金插針更穩(wěn)定，無鉛更環(huán)保！全部工廠貼片機(jī)貼片，波峰焊焊接質(zhì)量更好，非一般手焊可比。全部預(yù)留都焊接，方便升級！
關(guān)于有客戶提到的RAMPS1.4控制板有沒有焊D1二極管的問題,在此說明如下:
以下內(nèi)容來自*使用說明:
1、Without D1 installed, or when the 12VIN is not connected, the Arduino gets its power from USB. If you want your kit powered without USB connected you need to solder in D1 OR connect VCC to your PSU.
譯:如果不安裝D1二極管，或者不連接12V輸入，Arduino從USB獲得供電，如果你不想連接USB，那么你必須焊接D1或者接VCC到你的電源
2、The VCC pin can be connected to your ATX's 5Vsb to continuously power the Arduino from your ATX power supply. You will want to make sure that D1 is not installed or cut out. The Arduino is not designed to be powered directly on the VCC rail and the VIN pin at the same time.
譯:VCC引腳也可以從你的ATX’S－5V電源供電，但這樣的話，D1就必須不焊接！因為Arduino不能同時從VCC和VIN供電！
3、Power Supply without diode
The 1N4004 diode connects the RAMPS input voltage to the MEGA. If your board does not have this diode soldered in, you can safely input as much as 35V. （The pololus can do up to 35V）
譯:二極管1N4004是用于RAMPS供電到MEGA,如果你的板子沒有焊接這個二極管，你可以安全的使用高35V的供電輸入
4、Power Supply with diode
If your board has a 1N4004 diode soldered in, do not apply more than 12 V to it. Original flavor Arduino Mega are rated to 12 V input. While Arduino Mega 2560 can take 20 V, it is not recommended.
譯:如果你的板子已焊接了二極管1N4004，那么你的供電電壓絕不能高于12V，原版的Arduino Mega的額定電壓是12V。不*使用更高的電壓供電。
5、D1 should only be installed if the 5A rail is powered by 12V. It can be omitted and the Arduino will be powered from USB. You will want D1 installed if you add components to print without a PC. To reiterate, D1 MUST be omitted if you are powering the 5A rail by more than 12V, or the power is not absoluy clean, otherwise you may damage your ramps.
譯:只有當(dāng)你的系統(tǒng)是12V供電的時候，你才安裝D1二極管，如果你的Arduino從USB供電，它是可以省略的，當(dāng)你的系統(tǒng)想脫離PC運(yùn)行時（不接USB），你需要焊接D1，需要重申的是，如果你的系統(tǒng)的供電電壓是大于12V的，或者供電不太穩(wěn)定的時候，D1二極管必須不接，否則會破壞你的RAMPS.
