Stable 3.3 V supply and breadboard pinout for nRF24 modules
The ET-C18 is built around the Fixes the #1 nRF24L01 problem — weak 3.3V rail — with a 600mA LDO and 10µF+100nF at the socket. It talks over SPI on a 1x8 breadboard header (nRF24 inputs are 5V-tolerant).
Designed in Dubai by ElectroTrical — the full schematic, BOM and design notes are published below.
Good for
- Reliable nRF24 links
- Wireless remote controls
- Sensor networks with RF24Mesh
