A couple of months ago, Turkey has shipped a number of TB2 drones; the same that have been used to devastating effect by the Azeris against Armenian forces last year.

Turkish made Ukrainian Bayraktar TB2 drones are probably one of the most effective weapons the Ukrainian army currently deploys against the Russian aggressors. They have already eliminated numerous Russian tanks and Ukraine has only 20 of them. Turkey has more than 200. 🇹🇷🇺🇦 pic.twitter.com/s02yvDpwA5

Also, I understand that Javelin anti-tank shoulder mounted missiles have been used to destroy a number of Russian tanks. Not independently verified, of course, fog of war and all that.
