For direct donations the only direct payment method is probably cryptocurrencies like BTC or ETH, which come with their own issues such as volatility, poor user experience and huge transactional costs.

The first can be resolved by using a stablecoin such as DAI, the second still limits your donors to people who have MetaMask installed and are relatively fluent in the cryptocurrency concepts. The last one however is basically a show stopper for micropayments.
