Kauj Ruam 3: Pin Cov Ntaub Ntawv - Cov Khoom Siv Hluav Taws Xob

DragonBoard 410c txhawb nqa:

+1.8V:

Tsav los ntawm ob PMIC LDOs, LDO15 thiab LDO16, txhua tus tuaj yeem muab 55mA. PM8916 tso cai txuas ob LDOs ua ke kom muab 110mA ntawm 1.8V.

+5V:

Tsav los ntawm 4A 5.0V tus lej hloov pauv (U13). Lub pob hloov pauv no ua rau ob leeg USB txwv cov cuab yeej tam sim no (txhua ntawm 1.18A max). Lub peev xwm tseem tshuav muab tam sim no tam sim no ntawm 1.64A rau Qhov Tsawg Tsawg Tshaj Tawm Txuas Txuas, rau tag nrho ntawm 8.2W.

SYS_DCIN:

Muaj peev xwm ua haujlwm yog pawg thawj coj saib xyuas lub hauv paus tseem ceeb lossis tuaj yeem tau txais lub zog los ntawm pawg thawj coj.

Kauj Ruam 4: Pin Cov Ntaub Ntawv - GPIO

96Boards cov lus qhia tshwj xeeb hu rau 12 GPIO kab kom ua tiav ntawm Qhov Tsawg Tsawg Tshaj Tawm Txuas Txuas. Qee qhov ntawm GPIOs no tuaj yeem txhawb lwm txoj haujlwm rau DSI/CSI tswj. 11 GPIOs tau xa mus rau APQ8016 SoC thiab ib qho GPIO txuas nrog rau ntawm PMIC.
