![[projects/30 key keyboard/Index|Index]] Following helpful build logs from [rafaelromao](https://github.com/rafaelromao/keyboards/blob/main/docs/rommana.md) and [safstromo](https://github.com/safstromo/keyboards/blob/main/buildlogs/rommana/rommana.md), so first, the list of all the items needed. - A soldering gun - A desoldering gun - 2 [Seeed Studio XIAO nRF52840](https://www.amazon.com/gp/product/B09T9VVQG7/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&th=1) — compute power for each board, also supports charging the lithium battery - 4 [7.5mm Pogo pins](https://www.amazon.com/dp/B09NKGVSZ8?ref=ppx_yo2ov_dt_b_fed_asin_title) — used to connect the power and ground for the Seedino to the MCU holder. I actually didn't end up using these, just soldered a wire from the Seedino Bat+ and reset directly to the MCU holder before soldering it in. - [24 AWG Wire](https://www.amazon.com/Fermerry-Stranded-Electrical-Silicone-Cables/dp/B089CRSLG8/ref=sr_1_4?crid=1F853DOEJ6GS9&dib=eyJ2IjoiMSJ9.3mZm5CKbtxKVdlukvNh8GSEXUU96m4cZ3lc2iuo7i2NHBDiaJSQ7eW046iV4X5nQBqeHkbeTQAOY1PQrMOSxi7KMvOoQDh_gSEwQtT2KFxbu-pK_jqsLvj758lPsHWjXAVdrXh7agf6wtNWSA8Mp2lbZ81S3opbOZyrw9foCNP6SDz-qju8rfHKkW6oq-bnm9amDEcPTr_EYbw8AH5uD1NO4Yh2lEofHBszq5B_JwJuPnQmcFUxIomO2OnTKsKc95R--BPoKRcxMiUd9uo7aWnmOVaRampfhn_FCcHwcc_w.z1vbwAoTd9iUsvMcGa5Z8Dwk9MEG6ssjEdgorG0sJyM&dib_tag=se&keywords=AWG+24&qid=1729992764&s=industrial&sprefix=awg+24%2Cindustrial%2C183&sr=1-4) — Wire - [Pin headers](https://www.amazon.com/gp/product/B07BRZG9JP/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1) — Ripped these out of their plastic forms used them to mount the Seedunio on the MCU - 2 [Push button](https://www.amazon.com/dp/B07H9ZSZD4?psc=1&ref=ppx_yo2ov_dt_b_product_details) — Used for the reset button - 2 [Mini Slide switch](https://www.amazon.com/dp/B0DBGQWT86?ref=ppx_yo2ov_dt_b_fed_asin_title) — Power switch for Seedunio - 30 [Diodes](https://www.amazon.com/dp/B09TKVYJL6?ref=ppx_yo2ov_dt_b_fed_asin_title) — Attached to each switch holder - 30 [Hotswap Sockets](https://www.amazon.com/gp/product/B0B4W9YMGM/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1) — Allows switches to be hot swapped - M3 heated inserts and screws - 2 3.7 rechargeable lithium battery - 2 Battery holder for the 3.7 rechargeable battery Then finally, got to send these [STLs](https://github.com/AlaaSaadAbdo/Rommana/tree/main/STLs) (Case 3D printing diagram) and [PCB](https://github.com/AlaaSaadAbdo/Rommana/tree/main/PCB) to a manufacturer to get printed/built, I ordered through JLCPCB, would recommend. When choosing the type of filament for the case, you must use filament compatible with heated inserts, PLA being a good choice. [[2. Soldering|On to soldering!]]
