A simulated blinking LED circuit using an astable multivibrator a.k.a "flip-flop" as a square wave generator.

Two separate simulated circuits which demonstrate how step-up and step-down type transformers work.

Single M5Stack Cardputer ADV HAT integrating CC1101 sub-GHz radio, nRF24L01+ PA/LNA 2.4GHz radio, LoRa RA-02, and PN532 NFC with shared host interface, 3.3V power distribution, decoupling, and RF layout constraints.
