- A maximum transmission power 15 dbm
- Operating Frequency 2.4 MHz – 2.497 MHz
- Bluetooth Built-in
- New System on chip (BCM2837 reported to be 1.5x speed of previous gen)
- Chip is now 64bit ARMv8 QUAD Core 64bit processor
- MicroSD Card swapped out. Not more annoying spring ejection system that breaks.
- Position of status LEDs has changed (there is a chip antenna where they used to be).

- hello_there 11y agoNo mention of the amount of RAM anywhere.
- hatsunearu 11y ago1GB of LPDDR2-900, the same as before.
- nullc 11y agoThats too bad, Odroid C2 has 2GB ram (and is 4x a53 @2ghz, with gige) and is only $5 more list. (And, if you compare with prices in stores that have it available, is actually cheaper).
- alistproducer2 11y agoUnless what was typed is not true, I disagree with the downvotes. I'm someone thinking about getting a pi and I find information on alternatives helpful in making my decision.
- niutech 11y agoThere is also Orange Pi Plus 2 with 2GB RAM, 1.6GHz, WiFi, SATA, GbEth for $49.
- mahyarm 11y agoIs the audio any good? Would it compete on the level of an airport express?
- micheljansen 11y agoIf it's the same as the previous models: no, the audio of the Raspberry Pi is pretty rudimentary (it uses PWM) [1]. However, you can use an external DAC to improve this.

- augustk 11y agoA couple of years ago I bought a Raspberry Pi 2 to use as a music server. However, when playing through a Benchmark USB DAC I hear pops and clicks in the audio. Instead I bought a Cubox and use its Toslink output which works perfectly. Does anyone know if the USB audio issue have been fixed in the third version of the Raspberry Pi?
- mindslight 11y agoConnecting the analog audio of the RPi (1B) to my receiver causes the receiver's CPU to slow down to the point where it is unusable! It looks like the RPi puts out a DC-biased signal, and the receiver is seriously lacking input robustness. The two devices were also connected via HDMI, ruling out ground issues. I've since moved the music setup to also use HDMI (the DAC in the receiver is bound to be better anyway), but sheesh, be warned.
- txdv 11y agoToo bad it still doesn't have SATA, USB3 and Gigabit Ethernet.But this is already big step forward, wifi, bluetooth and a better cpu for the same price. The next generation will look even more promising. Currently I am just using my obsolete wifi dongle for my rasp
- LeoPanthera 11y agoIf it had all those things it would be a PC, with a price tag to match. If you need those things, build a PC.
- astannard 11y agoThe Orange Pi 2 Plus has sata and about the same price
- tehbeard 11y agoSATA via USB though? http://linux-sunxi.org/Xunlong_Orange_Pi_Plus#SATA http://linux-sunxi.org/Xunlong_Orange_Pi_Plus#SATA
- flowless 11y agoExactly. And limited to 15MB/s writes.
- voltagex_ 11y agoI haven't seen anything with directly connected SATA outside of iMX6 boards, and the pins aren't always connected. What did the Ax0 based Cubieboards use?
- makomk 11y agoThe original Cubieboards used on-chip AHCI SATA controllers. Allwinner dropped it from their newer chips, presumably because they're targeting tablet use and there's no need for them.
- digi_owl 11y ago2.5A? That fills me with worry, as i have yet to see one of those that do not assume the device will be Apple, and thus implement their signaling on the data pins.
- Tepix 11y agoThe original quote is: "This time round, we’re recommending a 2.5A adapter if you want to connect power-hungry USB devices to the Raspberry Pi." Sounds like you'll be find if you use the original 2A power supply and NOT connect power hungry stuff.
- pauly 11y agopreviously you'd have had a wifi dongle in one slot, plus then maybe mouse and keyboard... likely to be fine with the same power supply for the same use cases as before. Don't try and run your christmas tree off it.
- arm 11y agoYeah, AdaFruit¹ seems to agree: “Lastly, there’s an upgraded switched power source that goes up to 2.5 Amps instead of just 2 Amps - allowing your Pi to power even more powerful devices over USB ports. Note: Our 5V 2A power supply still works great with the Pi 3. For most uses, you don't need 2.5 amps of power and our 5V2A supply should be sufficient.” Still, it would be nice if they did make/source a generic USB wall adapter that can supply 2.5 A of current. Hopefully, this new Raspberry Pi will increase the demand for such a thing. ―――――― ¹ — https://www.adafruit.com/product/3055 https://www.adafruit.com/product/3055
- Daneel_ 11y agoThey do; it's a 2.5A, 5.1V adaptor. I've ordered one myself (from here: http://au.rs-online.com/web/p/plug-in-power-supply/9098135/?origin=PSF_430702|acc http://au.rs-online.com/web/p/plug-in-power-supply/9098135/?...)
- huskyr 11y agoI'm so happy it has builtin wifi. No more finicky dodgy USB dongles that get lost!
- nkozyra 11y agoNo kidding, it was otherwise such a simple thing to tuck away and use even for GPIO/breadboarding projects, but then you had to find one or two dongles to handle wifi/bluetooth turning the whole thing from handheld to a cluster of wires, dongles and connectors. Massive improvement if that was all that happened.
- niutech 11y agoIt is still a cluster of wires - hdmi, power, usb, audio. USB WiFi & BT dongles are as small as 5mm outside the socket.
- wallacoloo 11y agoThanks for the detailed summary. > Same GPIO To clarify, this means exactly the same GPIO capabilities (no extras like analog inputs, etc), as opposed to full GPIO compatibility with previous generations? Also, any idea when documentation for the new SoC will be released (i.e. the equivalent of this, for the bcm2837: https://www.raspberrypi.org/documentation/hardware/raspberrypi/bcm2835/README.md https://www.raspberrypi.org/documentation/hardware/raspberry...)? Said documentation could, of course, answer the above question, but I can't find any yet.
- fanf2 11y agoExactly the same capabilities, though very low-level code might notice a difference because the main UART is now used for Bluetooth, so the GPIOs use the mini-UART which is apparently affected by overclocking.
- lordcorusa 11y agoMicroSD Card swapped out. Not more annoying spring ejection system that breaks. What does this mean? I didn't see anything about this in the announcement.
- pjc50 11y agoThe cardholder used to be a push-to-eject type, but apparently this was unpopular. Sometimes failing to eject, sometimes too easy to trigger (since it's protruding and not recessed in casework). Now it's just a friction fit.
- lordcorusa 11y agoThat's interesting. The original Pi was a friction fit (full-size SD card), but that was unpopular, so they switched to the spring-eject system for Micro-SD. Seems they cannot make up their minds which one they prefer.
- fanf2 11y agoAccording to the third post on this forum thread [1] they don't do fat channels so WiFi is limited to 20 MHz / 72 Mbit/s. The CPU is Cortex-A53. Cache sizes reportedly same as on the Pi 2, 32K data + 32K code + 512K level 2. RAM still 1Gbyte 900MHz.
