Overall, if you’re looking for an affordable development board to the Raspberry Pi 5 Compute Module then is a solid choice. Compute Module 5 Boards Review Features & Functionality Price Whats in the box User instructions & Documentation Ease of use Availability Asthetics Build Quality Packaging Environmental Summary Scoring Compute Module 5 Boards Review Waveshare have released a number of affordable Compute Module 5 boards. These boards are compatible with the Raspberry Pi Compute Module 5 modules including the eMMC, WiFi enabled as well as Lite versions. Features & Functionality The CM5 Nano A1 is a paired back version of the CM5-Nano-B board. It has the same form factor but lacks the USB-C port and RTC connector. It is a great option for those who want to use the CM5 in a compact design without the need for additional features. It has the same form factor as the Raspberry IO Dev board. The Built-in NMVe is a nice touch. The 2x Fullsize HDMI is better than the 2x Micro HDMI connectors on the regular Raspberry Pi. Built-in RTC Clock battery socket is also a welcome addition. The Power over Ethernet (PoE) is the main feature of this board, meaning you can power if from the Ethernet cable, as long as the switch it is connected to has PoE enabled. 40 pin GPIO Header 4x USB A Ethernet socket with PoE 2x HDMI USB C Power / flash firmware 2x MiPi Display/Camera SD Card slot RTC Battery socket Fan connector NVMe Socket Power & Boot buttons Price The CM5-PoE-BASE-A is priced at $31.99 2 for the version without PoE and $44.99 with PoE. , making it an affordable option for those looking to use the Compute Module 5 in a compact design. Whats in the box In the box are the CM5-PoE-BASE-A board. User instructions & Documentation The instructions for the board are available on the Waveshare Wiki. The documentation is clear and easy to follow, though I did get a little confused about how to flash the eMMC so that the Raspberry Pi can boot from the internal storage. Ease of use The boards could not be simpler to use, just plug in the CM5 module and you’re away. Availability Available world wide; check out the list of resellers on Waveshares website https://www.waveshare.com. Asthetics Dev boards are straightforward and functional, these are designed to test our features for smaller boards so tend to be large and have lots of space around the components. They aren’t going to win a beauty competition. Build Quality The PCBs and components have a solid connection and the overall board seems pretty robust. Packaging The packaging was simple and functional. The boards were well protected in the box and there was no damage to the boards during shipping. For extra points the plastic bubble wrap could be replaced with shredded cardboard or paper. Environmental The packaging could be made a little more environmentally friendly by using shredded cardboard or paper instead of plastic bubble wrap. Summary Overall, if you’re looking for an affordable development board to the Raspberry Pi 5 Compute Module then is a solid choice. Scoring Below is the Kevs Robots review framework. First, each product is scored out of 5 for each of the 9 areas. The total score is then calculated by adding the scores for each area and dividing by 9. The total score is then rounded to the nearest whole number. Scoring area 1 2 3 4 5 Price Very Expensive, verging on not worth it Expensive, but worth it for the value add Affordable, similar in price to competitors Cheap / great value for the parts and features Free / Very low cost Ease of use Hard to use, complex operations requiring multipe steps Many steps, some of which as complex. Some steps to construct or operate, some of which are complex Few steps, simple to do Very easy to use / use is obvious and clear Functionality Very little innovation or usefulness Does less then you’d expect, but still useful Practice, does what you expect but no more Quite a few innovative functions, does more than you’d expect Amazing features & innovation, industry leading Availability Very difficult to get hold of any variation or version Little available; some variations or versions are available Available in some countries and stocks mostly available Available in most countries & mostly in stock, short wait for stock replenishment All versions and variations widely available in all countries & in stock Aesthetics Design is not pleasing to the eye; poor colour choice, parts do not fit together, no cohesive design Design is acceptable, some elements do not work together well Design is functional, no overall cohesion Design is functional with some flair, most elements work together well Very pleasing to the eye, complimentary colour choices, great fit and finish, with an overall cohesive design Build Quality Poor construction, with gaps or overlapping parts.
