For the display we are using https://www.digikey.ca/en/products/detail/seeed-technology-co-ltd/104020208/10667534?s=N4IgjCBcpgrALFUBjKAzAhgGwM4FMAaEAeygG0QBmWANgE4wAOEAXSIAcAXKEAZU4BOASwB2AcxABfIgFoATEhCpIggK6ES5ELFbSQMmouVqNpSBUq7ZEaEvTZ8RMxTh0A7CCJyabxC0l6CuYgADIAwgAiAASsRDq27FBgHImQcrB6hrZCACY8MmAADIWeIFw8pZwAnux4PBg4qAFAA . Its cheap and has the supporting electronics on board to make integration easy. It interfaces through I2C so we can throw it on the same bus as everything else and not waste more pins. It also has nothing on the bottom so it can sit flat on the assembly. This does however mean it has a connector on the too for I2C. This still makes integration easy since we only need to have a connector on the board to interface with the display. To keep the connector 1:1, we are using the Grove 4 pin connector, which is on the display. I am picking the surface mount version to keep it consistent with all the other connectors. Here is the selected connector and cable needed to join the board and the display. Note that these parts come in packs of multiple units, so do not order 5 of them for 5 boards. See how many the pack comes with when choosing how many to order.
