Raspberry Pi Hobbyist Assemble!

Bro, I believe the key there is the power supply gyud. If you can use a 5V 2A or 2.5A power supply...there's no problem if you use all 4 USB ports.

if mga 1A or less lng ang power supply...then that's quite dangerous...kulang rah...bisag ato pa tingale eh tweak.

Sakto ka bro, pero sa usa ra na cya ka side sa equation. Mura ni cya ug chicken and egg na situation bro. "Magdepende ba ang imong power supply spec sa maximum requirement sa imong device (rpi) + peripherals (i.e., hard drive/s, camera, sensors, etc)" or "magdepende ang peripherals or external devices na imong gamiton relative sa power supply na imo gipalit para sa imo rpi"? Provided na you know your device's power limitations.

Tagaan tika ug scenario (hinimo ko lang). I know na ang ako RPI 2 power supply max output current kay 2A. Typically ang rpi 2 kay mokaon na cya ug ~700mA - wala pa nay nakasaksak na external devices. Wala ko kahibalo na ang maximum current na we can draw from the USB ports diay (all 4 combined) is limited to 600mA max. Naa koy keyboard, mouse, wifi adapter na nakasaksak (working kay less than 600mA man ila current drawn) sa akong rpi. Now, nakapalit ko ug barato na portable usb hard drive online. Sa akong huna-huna, since 2A ang akong power supply, wala gyud koy prob kung ako isakisak ang bag-o nako na napalit na hd. So, akong gisaksak, without checking the hard drive's current spec; I did not even checked my wifi adapter's current spec. So unsai nahitabo? Dili madetect ang hard drive; wala na migana ang wifi, etc. So reverse engineering dayon. Then found out na ang hard drive diay na akong gisaksak kay nag need at least 1.5A for read/write. Karaan diay na SATA drive na may SATA to USB ang sulod sa case. Bisan ilisan pa nako akong power supply ug mas taas na spec, walay epek kay ang limitation tua man sa USB interface.

So dapat hibaw-on pud ang power requirements (rpi + external devices) ug ang mga limitations para dili mausik ang kwarta nya dili mga larot ang ato buhok ug debug .

Taasa oi... kayuring ang agi

thanks for the tip bro that 600mA is the max current that can be drawn from all 4 USB ports...

I want to share also that 700mA is quite too high for rpi2 without any peripherals.

i'm using a 10000mAH powerbank as the powersource for my rpi2.

It can operate for more than 20 hours (connected via ethernet cable) and i'm accessing via SSH, downloading torrent just to the SD card, serving a wiki page, running some scripts, etc.

20 hours X 700mA = 14000mAH

meaning bro, ni-exceed cya sa capacity sa ak0 powerbank...theref0re I believe bro rpi2 in its base form without peripherals operate within 300-400mA only 700mA is the max current that it can draw from power source I believe. ma0 gi state na sa manufacturer to have at least 700mA or good minimum of 1A power supply in order to protect the device also and prevent it from not functioning well.

haha... correct ka sa "~700mA" na ako namention bai... basin ma-misunderstood sa uban; I'm referring to peak current (naa to cya display - not really without peripheral). Dili to cya average current drawn over time. Ang formula nga imo gi-state above (thumbs up) makahatag lang nimo ug idea how much was your average current drawn over a period of time; but not the peak current or maximum sustained current na gi-draw sa imo device for a specific period of time / process.

Nice sharing maayo ni na topic dili mingaw.

ah, 0k...medy0 may pagka arte diay ning kaha-a....hehehe. murag law0m cya tanaw0n. or basin sa angle lng sa pagkuha nim0 sa piktyur.

kanang buffal0 nim0 diha? unsa na router or st0rage?
