Board Comparison

The parameter table can be listed in parallel because the specifications of the development board can be quantified: main control model, main frequency, Flash and RAM, GPIO quantity, wireless capability, power supply mode, and onboard debugger. Put several boards into the same table, and the differences will immediately become apparent.

But what really determines the selection is often not the largest number in the table. The same standard is 240 MHz, with or without hardware floating-point, with or without PSRAM extension, and whether it can run MicroPython or RTOS, the actual experience varies greatly; Whether it is possible to use both a camera and an SD card with the same 30 GPIO is another matter.

So this table is suitable for exclusion, not for making decisions. First, use it to screen out boards that do not meet the hard conditions, and then return to the single board details page to view the pin reuse table, schematic, and known issues.

• Pre order peripherals：For projects that require cameras, Ethernet, and CAN, filtering by external devices is more effective than filtering by main frequency.
• Looking at the power supply again：Battery power supply should focus on sleep current and LDO/DCDC efficiency, which are rarely listed on the homepage.
• Finally, let's take a look at ecology：At the same price point, a 20% increase in document completeness and community Q&A volume has a greater impact on development time.
