For many projects, dedicating an entire PC to one task is redundant. This is where a single-board computer comes in handy. Raspberry Pi’s foundation in the SBC (Single Board Computer) industry is rock solid. It’s undisputed, with over 300,000 boards released since its launch in 2012. Its small size, affordable price, and PC-level performance make it ideal for beginner programmers and DIY project makers.
Due to the popularity of the Raspberry Pi, many manufacturers have joined the ranks, and many other similar single-board computers have appeared over the years. If you’re looking for a board identical to the Raspberry Pi but with different specs (such as better performance or lower cost), this article provides a multi-dimensional comparison of the Raspberry Pi 4 and the DSGW-270 DIY gateway. The DSGW-270 DIY IoT Gateway is an upcoming developer-oriented IoT gateway whose essence is similar to the Raspberry Pi4.
Positioning of Raspberry Pi
In the era when PCs cost hundreds of dollars, the cross-border specification definition and the ultra-low price of 30 dollars are the reasons why everyone initially accepted the Raspberry Pi. But there have been many products similar to Raspberry Pi on the market, but Raspberry Pi has always had a place in the market. As you can see, low price isn’t the only factor behind the Raspberry Pi’s success. Raspberry Pi has the following significant advantages:
Excellent community operation meets the learning needs of developers. There are hundreds of official/unofficial websites/BBS communities/instant communication groups on the Internet, and developers can easily understand the latest developments of the Raspberry Pi and communicate with the great gods.
Rich application cases and peripheral options meet the needs of developers: you can easily find application cases such as smart cars/crawling robots/TV boxes/NAS/bypass routers made by Dashen on the Internet and buy cheap or even second-hand accessories.
Mature, reliable, and stable software and hardware system design to meet commercial needs: The dedicated OS Raspbian has rich and reliable documentation and a long maintenance cycle and is. Generally, a rookie cannot encounter bugs.
The hardware design is professional and stable. For example, the PCB flat horn antenna of Raspberry Pi 3/4 is textbook-level, and its signal strength and stability are far better than the external antennas of many development boards.
DSGW-270 DIY IoT gateway is an IoT gateway for developers. Its core is similar to Raspberry Pi4. Using Rockchip RK3568 processor, based on ARM quad-core Cortex-A55 core, 2 GHz operating frequency. It can support multiple systems like Linux, Debian, etc. It has great external interfaces, HDMI, USB, and so on. It differs from the Raspberry Pi in the following ways:
1. Regarding the product form, DSGW-270 has achieved the finished product and has a structure ID. The Raspberry Pi 4 is just a development board. DSGW-270 is more oriented towards C-end users. Based on the product, developers can directly develop software without matching other hardware peripherals.
2. Raspberry Pi 4 is a single PCBA, and its capabilities are fixed. In contrast, the DSGW-270 adopts a modular design. Each wireless module adopts a modular design, and users can choose the best configuration to meet their needs, making the cost performance higher. Not only the protocol module but also the CPU, structure, and other hardware can be replaced according to the conditions, which can meet the needs of the user’s usage scenarios to the greatest extent.
3. In terms of core performance, Raspberry Pi uses Broadcom BCM2711, quad-core Cortex-A72 (ARM v8) 64-bit SoC @ 1.5GHz. DSGW-270 adopts RK3568 ARM® Quad-core 64-bit processor, Quad-core Cortex-A55 @2.0GHz. Both CPUs have their advantages. The 28nm chip of the Raspberry Pi means more powerful graphics performance, while the 22nm process chip of the DSGW-270 can make the power consumption lower and the performance stronger.
4. The Raspberry Pi 4 cannot support the Internet of Things and must be built by itself. The finished product supports Lora, Zigbee, Z-Wave, and Sigmesh and can be adjusted quickly. The Raspberry Pi 4 cannot support the IoT by itself and must be built with an external kit to complete the IoT.
5. Raspberry Pi 4 cannot self-support RF, while DSGW-270 realizes antenna self-integration. Its built-in RF antenna saves users the purchase of expensive RF test instruments.
DSGW-270 saves developers a lot of trouble and is a relatively mature product. The advantage of the Raspberry Pi is scalability, and the imagination can create infinite possibilities for DIY. Developers can choose which product to buy according to their actual needs.
