Most hubs seem to deliver more than the specified current but there's no guarantee. Check the power supply rating, it must be enough to supply everything that's connected to broadcom bcm2835 hub.

Raspberry Pi - Wikipedia

Adding a USB hard disk drive. A HDD will take quite a lot of power as it starts, maybe an amp or more. It the power supply for this also supplies the Pi broadcom bcm2835 this could overload things and cause trouble.

The Pi cannot deliver this amount of power. Simpler budget keyboards may be better.

BCM - Raspberry Pi Documentation

Broadcom bcm2835 the system works with no keyboard attached but not with a keyboard then it's worth trying a different, simpler, keyboard. Summary If you are having unreliable operation the first thing to do is check your power supply.

Use a good quality micro USB cable. Cables are notorious broadcom bcm2835 giving trouble so be prepared to swap for another one. Not all power supplies will deliver what they claim.

This capacitor helps stabilise the DC power on the board, but for some it has also become a place for their thumb when removing the Raspberry Pi's power lead; unfortunately, this can result in the capacitor breaking off! It has been stated in the forums that the type of capacitor used for C6 will be changed on later Raspberry Pi models for one with sturdier leads.

If you do break off your C6 capacitor, it's highly likely that your Raspberry Pi will still work properly, unless you have a particularly unstable power supply, but the general advice is to not use C6 as a leverage point when removing the power connector and also take care when storing or transporting your Raspberry Pi if it's not fitted in a case - try not to stow the board where C6 could be knocked by other items - for example in a laptop carry case or in amongst some books.

Capacitor C6 ringed It's unlikely that replacing a broken off C6 capacitor will be covered under warranty, but fortunately they are easy to replace if you have average soldering skillsbut remember that reworking your Raspberry Pi will void its warranty too.

These boards are approximately credit-card sized and represent the standard mainline form-factor.

Raspberry Pi Resources

A "Compute Broadcom bcm2835 was released in April for embedded applications. Byit became the newest mainline Raspberry Pi.


This allows the use of the Pi in hard-to-reach places possibly without broadcom bcm2835. Hardware[ edit ] The Raspberry Pi hardware has evolved through several versions that feature variations in memory capacity and peripheral-device support.

RPi Hardware

Other pins that were already previously enabled stay enabled. It's not necessary to do that, you can just mmap the file directly, so I've removed the mallocs and frees. I've also modified delayMicroseconds to use nanosleep for broadcom bcm2835 waits, broadcom bcm2835 a busy wait on a high resolution timer for the rest.


This is because I've found that calling nanosleep takes at least us. You need to link using '-lrt' using this version. Reported by Ben Simpson. Broadcom bcm2835 by Sebastian Loncar. Also the license of the raspberry pi firmware is restricted to use on raspberry pi products, so to remain within the license you would have to make your own firmware builds from the materials broadcom provide under NDA.
