+
+### TINA2 WIFI / TINA2 BASIC
+- Outdated older models.
+- Called V2/V3 hardware by the manufacturer (Weedo / Weefun / Entina?).
+- The TINA2 WIFI is the standard TINA2 with ESP32 WIFI module installed. Supports remote control, sending files via WiFi, and online 3D model library.
+- The TINA2 BASIC is the lite version of the TINA2 with no WiFi module or protective shell.
+- Uses motherboard R62A/R62AS with ATMEGA2560 MCU.
+- Firmware files are 8-bit, identified by the "`.hex`" extension.
+- [Official TINA2firmware repo](https://github.com/weedo3d/TINA2firmware)
+
+### TINA2 UPGRADE
+- V7 hardware.
+- Current "basic" model. Sometimes called TINA2 or TINA2 BASIC, which adds to the confusion.
+- Uses motherboard R72A/R72B with a GD32F103RET6 MCU.
+- Firmware files are 32-bit, identified by the "`.bin`" or "`.wfm`" extension (proprietary format). These firmware files are NOT compatible with the older ATMEGA2560-based models, or vice versa. If your firmware update fails, it may be due to this mismatch.

+
+### TINA2S
+- Current "WiFi" model. Compared to the base TINA2 UPGRADE model, adds WiFi and a heated bed.
+- Uses motherboard R72H/R72P with a GD32F103RET6 MCU.
