MRT 402 — FIRST BOARD SETUP CHECKLIST

[ ] I have a Node ESP32 board, USB data cable and desktop Chrome.
[ ] AA batteries, motors and servos are disconnected for first setup.
[ ] My data cable connects the computer USB port to Node DOWNLOAD.
[ ] New board: I chose Update firmware, confirmed the board and waited for verification.
[ ] I kept USB connected while the original board was saved, firmware written and memory checked.
[ ] My Node USB program has two separate green start stacks and stop all motors below each.
[ ] I saved an editable .sb3 copy and can reopen it.
[ ] I built my program, confirmed the board and clicked Upload to board.
[ ] I saw Program saved, checked and started.
[ ] I know that this stop-only program should not move anything.

Firmware prepares the board. Code upload changes its instructions. Save keeps editable blocks.
