Comparison
Robin nano V3 is an upgraded version of Robin Nano V2.0. The upgrade changes are quite large, including upgrading the MCU to the M4 core, and adding support for USB disk.
| ITEMS | Robin Nano V2.0 | Robin Nano V3.0 |

| MCU | STM32F103VET6(72MHz) | STM32F407VGT6（168MHz） |
| FLASH/RAM | 512KB FLASH/64KB RAM | 1024KB FLASH/192KB RAM |
| USB Disk | Not support | Support |
| TF card | Support(SDIO) | Support(SPI3) |
| WIFI connect | USART1 | USART1+SPI2 |
| Virtural USB Device | Not support | Support |
| Motor interface | 5 axis | 6 axis(Two Z axis share the same driver) |
| PWM FAN(s) | 1 channel | 2 channels |
| PWM TTL | Not Support | Support |
| Independent serial port | Not support | Support(UART3) |
| Power TVS protect | No | Yes |
| Expansion SD slot | Support | Not support |
| MAX31855 interface | Support | Not support |
| EEPROM | 4KB AT24C32DM | 4KB AT24C32DM |
| SPI Flash | 8M W25Q64JVSIQ | 8M W25Q64JVSIQ |
| LCD support | MKS TS35/MKS H43*/LCD12864/LCD2004 | MKS TS35/MKS H43/LCD12864/LCD2004 |
*Note: As MKS Robin Nano V2.0 doesn't has an independent serial port, so if using with the MKS H43, V2.0 cannot work with Wifi module, but V3.0 can make it.
The hardware design is openned source on : https://github.com/makerbase-mks/MKS-Robin-Nano-V3.X/tree/main/hardware
The same as the Robin Nano V2.0, firmware of MKS Robin Nano V3.0 is also based on Marlin 2.X. Actually, we directly use the same respository:https://github.com/makerbase-mks/Mks-Robin-Nano-Marlin2.0-Firmware. Just modify the type of motherboard to compile the related firmware.
