- **tasmota-zbbridge.bin** = The dedicated Sonoff Zigbee Bridge version.
- **tasmota-minimal.bin** = The Minimal version allows intermediate OTA uploads to support larger versions and does NOT change any persistent parameter. This version **should NOT be used for initial installation**.
Binaries for ESP8266 based devices can be downloaded from http://ota.tasmota.com/tasmota/release. Binaries for ESP32 based devices can be downloaded from http://ota.tasmota.com/tasmota32/release. The base links can be used for OTA upgrades like ``OtaUrl http://ota.tasmota.com/tasmota/release/tasmota.bin``
The attached binaries can also be downloaded from http://ota.tasmota.com/tasmota/release for ESP8266 or http://ota.tasmota.com/tasmota32/release for ESP32. The links can be used for OTA upgrades too like ``OtaUrl http://ota.tasmota.com/tasmota/release/tasmota.bin``
