OpenEVSE board for juicebox

I am considering buying the new juicebox retrofit board to get myself started in the OpenEVSE world. I have exactly zero experience with OpenEVSE, and some experience with DIY electronics (ESP-home).


Could someone help me figure out, before I jump in:


* Is that board all-inclusive, or is any additional hardware required?

* Is it compatible with a screen, or at least a button?

* Is it pre-flashed, or do I need to get a programmer too? Which one?


Thanks in advance.

Can someone advise the pinout and what connecter to connect the 2 temp sensors to.


"

Temp 2 is MCP9808 sensor connected to the Controller. When installed it is used for enclosure temperature throttling and Emergency Cutoff.


Temp 4 is MCP9808 sensor connected to WiFi, It is for situational awareness and logging.

Thanks in advance.

@Troy


The connector is JST SH on the sensor side and JST PH on the controller side.


Here is a diagram with the pinout.

Thanks however this is not the board that the juicebox is using, plus there are 2 temp connections, are you talking about connecting to the I2C connector and if so what do you connnect the second temp sensor to?

@Troy We used the same connector and pinout for the I2C on the OpenEVSE and Juicebox boards so all the accessories would be compatible. The kit we sell works for both and includes the correct cable. https://store.openevse.com/collections/all-products/products/temperature-sensor


Only one sensor is needed. Temp 2, provides temperature throttling and shutdown. Temp 1 and 3 and no longer supported. Temp 4 can only provide a value no throttling and shutdown. If you really want Temp 4 it is just a JST SH to JST SH straight through.

I guess this is the catch-all thread for this. I bought a Juicebox off EBay and an OpenEVSE board. Have installed the board. Had to order a new power cord because it looks like they just cut it off. Hots are 6 AWG. But they don't fit in the GFCI coil. They're both supposed to go through the GFCI coil right? Is there any (reasonably safe) way around that?


I needed a 6 foot cord, so I went with 6 AWG, thinking it'd be safer. Now I've cut the terminals off to put on my own ferrules. Great.
