Raspberry Pi 3A+ review
In this episode of HPR, I will do a quick review of the Raspberry Pi 3A+, the latest release of the Raspberry Pi foundation.
The Raspberry Pi 3A+ has almost the same hardware as its big brother/sister the 3B+ :
- BCM2837 BO SOC (system on chip), a quad core 64-bit ARM v8 processor, running at 1.4 GHz
- On board wireless :
- WiFi : 2.4 and 5 GHz 802.11 c/y/n/ac
- Bluetooth : 4.2 and BLE
- MicroSD card for storing the operating system and the data
- Full size HDMI connector
- 3.5 mm jack connector for audio and composite video output
- MicroUSB connector for the power supply
- 40-pin header with the same pinout as every other Raspberry Pi
The differences are :
- Only one full size USB connector, instead of four on the 3B+
- No ethernet connector
- Only 512 MB or SDRAM instead of 1 GB on the 3B+
The Raspberry Pi 3A+ is 6.7 x 5.6 cm (2.6 x 2.2 in) and 11 mm high (.45 in). But if you plug a ribbon in the header, then it takes a lot of space.
In this case, it’s probably better to unsolder the header, and solder a right angle header in place, so the pins are pointing to the side of the board and not upwards
With a bit of caution and the help of some desoldering wick, it’s not a complex operation, because there is no component near the GPIO header.
Of course if you plan on using a HAT, then you’re better off using the straight header. The Raspberry Pi 3A+ is actually the same size than a standard HAT.
Since the Raspberry Pi 3A+ doesn’t have an ethernet port, I think I will not use it for server stuff like Mosquitto or Pi-Hole, for which a good network connection is required. Also, those servers sometimes need a keyboard and a mouse, and with only one USB port, that’s not too practical.
For me, the A+ will be used to upgrade projects currently using a Raspberry Pi ZeroW, and for which I need a little more power. The on board WiFi and the small form factor, combined with the extra power, makes the 3A+ an ideal replacement for the ZeroW.
