MIT is a software licence and does not map onto board designs, so the hardware repository is now CERN-OHL-S-2.0 and the firmware and app are Apache-2.0. Also broadened the Bridge description: the firmware targets ESP32-C6 / S3 / C3, and the wireless board uses a XIAO ESP32-C6, not only the S3. --- 1209/9210/index.md | 8 +++++--- 1209/9211/index.md | 11 ++++++----- 2 files changed, 11 insertions(+), 8 deletions(-) diff --git a/1209/9210/index.md b/1209/9210/index.md index be2a495b..ebed9b38 100644 --- a/1209/9210/index.md +++ b/1209/9210/index.md @@ -2,12 +2,14 @@ layout: pid title: Mimic X owner: kunichiko -license: MIT +license: Apache-2.0 (firmware, app) / CERN-OHL-S-2.0 (hardware) site: https://github.com/kunichiko/MimicX-firmware source: https://github.com/kunichiko/MimicX-firmware --- A USB device that receives commands from a smartphone over USB-MIDI and emulates retro-PC HID peripherals (ATARI joystick, Sega Mega Drive 6-button pad, Sharp X68000 keyboard and mouse).
