![]() I’m currently hauling mine wherever I go (so it doubles up as a wireless AP whenever only Ethernet is available), and I actually see this new gen. It would have been interesting to see how the new Airport Express compares in size with the old one.

It’s a beautiful little box which has thus far performed quite well in all our tests. Powering the AirPort Express from an external power supplyĪll in all, the design of the new Express appears to be a mix of both old and new. If your power supply ever dies, you can just wire a 3.3VDC wall supply directly to these positions on the logic board and it’ll happily power up: One thing to note here is that power is delivered from the power supply to the logic board by way of the 2 screw mounting holes that overlap between the boards (labeled V0 and GND on the PSU). The compactness of this little board is quite striking, with the main transformer suspended through the PCB to shave off a few millimeters of thickness. Previous Expresses used a dual-output 12VDC/5VDC supply made by Samsung. On to the power supply, a 3.3VDC / 2A module made by Delta, similar to the AppleTV 2. This chip is similar to the Cirrus Logic CS4344 used in the previous model, but should be a improvement over the Burr-Brown PCM2705 used in the original 802.11g Airport Expresses More pertinent to our customers, the audio digital to analog converter is an all-new 24-bit/192khz Asahi Kasei AKM4430. Presumably this is built directly into the CPUs now. Notably absent is a Flash memory chip, which the old models used to store their firmware and user settings. The main chips are an Atheros AR9344 and Atheros AR9582, with 64MB of RAM from a Hynix H5PS5162GFR. ![]() The logic board itself is not too different from previous Expresses. There is a power supply board and a logic board, and one giant anodized aluminum heat sink. Inside the Airport Express is rather similar to both the AppleTV 2 and the old Airport Expresses. A putty knife might have been better, but the few remaining functional tabs still hold it in place after reassembly. That said, I broke nearly all the tabs holding it on in the process. The bottom case pops off with just a thin screwdriver around the edges. With only one way to find out, we ordered our test units as well as one to go under the knife screwdriver. With the announcement of the new Airport Expresses (they work great with Airfoil), and their obvious resemblance to AppleTV 2s, my first thought was “I wonder if it’s just an AppleTV 2 inside?”.
