I am trying to understand the performance differences between the RAK11300 and RAK4631. Can anyone help me clarify?
From the specs, I understand the following:
- RP2040 ARM CPU
- Dual ARM Cortex M0+ cores (no mention of FPU)
- 133MHz clock speed
- 264KB SRAM
- No onboard flash memory
- No wifi radios
- 256KB flash (2Mbit) see here
- Nordic NRF52840 CPU
- Single Core (ARM Cortex M4 with FPU)
- 64MHz clock speed
- 256KB RAM
- 1MB onboard flash
- Bluetooth radio
Am I correct in assuming that the RAK11300 offers more performance, both clock-speed-based and multi-core-processing, vs the RAK4631?
Regarding non-performance related features: other than the lack of built-in connectivity (radios) in the 11300, are there any other features offered by the 4631 that are missing on the 11300?
To summarize, I’m trying to decide which of these units to purchase for a project, based on features and cost.
