NHB Systems JL401-S3 4MB Flash 2MB PSRAM by NHB Systems

CircuitPython 10.3.0-alpha.2

This is the latest development release of CircuitPython that will work with the NHB Systems JL401-S3 4MB Flash 2MB PSRAM.

WARNING: On Espressif ESP32-S2 and ESP32-S3 boards with 4MB flash, CircuitPython 10.0.0-beta.0 and later require TinyUF2 bootloader version 0.33.0 or later. Older TinyUF2 bootloaders don't provide enough room for the firmware and cannot load it. See the Release Notes for more details, and see Update UF2 Bootloader below.

Alpha development releases are early releases. They are unfinished, are likely to have bugs, and the features they provide may change. Beta releases may have some bugs and unfinished features, but should be suitable for many uses. A Release Candidate (rc) release is considered done and will become the next stable release, assuming no further issues are found.

Please try alpha, beta, and rc releases if you are able. Your testing is invaluable: it helps us uncover and find issues quickly.
