Since STM32F411CEU6 chip is too expensive, due to the cost and customer demand.
We decided to use AT32F403ACGU7 as the new version of blackbill, with higher performance, larger memory and more affordable price.
However, we will still produce boards equipped with STM32F411CEU6, but we need to wait until the chip is at a suitable price.
