On the real board the WROVER sits in a socket at one end, and the forty pins come out in two rows 0.3 inch apart that straddle a breadboard's center channel, with a pair of tabs at each end that push into the rails. Mokxi draws it that way: the extension board is one part, the Freenove ESP32-WROVER board is another, and the WROVER goes on top of the sockets.
Placing it
Put the extension board on the breadboard so its two rows straddle the channel (its
bottom row in row e, its top row in row f), then drop the WROVER on the sockets
at the left end. The WROVER snaps one unit down and three across from the extension
board's corner, which is where its pins land on the sockets. A pin of the WROVER
then reaches the pin of the same name in the rows, with no wire.
Pins
| Pin | What it does |
|---|---|
| Rows (40 pins) | One for each WROVER pin, named as the WROVER names it. The bottom row is the WROVER's left header top to bottom, the top row its right header. |
S_ pins (40) |
The sockets the WROVER plugs into, one under each WROVER pin. Each is the same piece of metal as its row pin. |
R3V3, RGND1 |
The top rail tabs, printed EXT-3.3V and GND. |
R5V, RGND2 |
The bottom rail tabs, printed 5V and GND. |
Every GND pin is one net, as on the board, and so are the 3V3 pins and the 5V pins.
GNDb and 3V3c are the WROVER's own names for its repeated pins.
What the model gets right, and what it does not
It is wire. The board has no parts that do anything but connect: each socket pin is joined to its row pin, and the power pins are joined to each other. Nothing is simulated beyond that.
The rail tabs are read from a photo. Mokxi joins the EXT-3.3V tab to the board's 3V3 pins and the 5V tab to its 5V pins. If your board's tab is an input from an outside supply that is not joined on the board, tell us.
A WROVER that is not on the sockets is not joined. Move it a unit and its pins stop reaching the rows, as a board half out of its socket would.
Powering it
The WROVER runs from its USB-C socket. To feed the rails from a breadboard power module, place an MB102 breadboard power supply on the other end of the breadboard.
