- Mohato oa 1: Baseplate Strips
- Bona: Modular Display Element (MDE)
- "Modular Display Elements" tse 'ne lia hlokahala ho theha pontšo ea oache 'me tsena li tšoaroa hammoho le li-baseplate strips tse khaotsoeng ho tloha plate e kholoanyane.
- Lithapa tsa baseplate li lekanya 32(W) x 144(L) mm kapa 4 x 18 stubs' me e 'ngoe le e 'ngoe e feta e hokahane le li-MDE tse peli tse hokelletsoeng ho li-stubs tse ho MDE. Leha ho le joalo, bakeng sa matla a eketsehileng li-screws tse 'nè tsa M2 x 8mm li kentsoe haufi le likhutlo tse fetang ka har'a baseplate le ho kena ho MDE.
- Mohato oa 2: Schematic
- Sekema se bonts'a likarolo tse sebelisoang ho laola MDE's tse nang le 56 Neopixels.
- Likarolo tsa taolo li na le Microbit, RTC, Breakout Board, Phetoho le potoloho ea tšireletso.
- Boholo ba soldering bo tsepamisitsoe ho Neopixels athe likarolo tsa taolo li amana haholo le li-jumpers.

- E letsetsa 'Time_split' e kopanyang lipalo tse peli tsa lihora le metsotso ho khoele e nang le litlhaku tse 4, e fetisa linomoro tse ka tlase ho 10 ka lefela pele.
E letsetsa 'pixel_time' - E ntšang litlhaku tse 4 ka ho latellana ho qala ka tlhaku ea ho qetela ho segment_value
- Joale Digit e na le boleng ba segment_list e boletsoeng ke segment_value.
- (Haeba segment_value = 0 joale nomoro = element [0] = 0111111)
- Inc = index x (LED_SEG) x 7). Moo index = ke efe ho litlhaku tse 4 e boletsoeng, LED_SEG = palo ea LED ka karolo ka 'ngoe, 7 = palo ea likarolo ka palo.
- Mofuta ona ke qalo ea li-LED tse lokelang ho laoloa bakeng sa sebopeho se nepahetseng.
- The for element e abela nomoro e 'ngoe le e 'ngoe ka nomoro ho ea bohlokoa.
- Haeba boleng =1 joale pixel e fanoeng ke inc e behiloe ho khubelu 'me e buletsoe ho seng joalo e butsoe o.
- Ha ho hlokahala li-LED tse peli karolong ka 'ngoe, ts'ebetso ena e phetoa makhetlo a LED_SEG.

Mohato 4: Back Panel
Likaroloana li khomaretsoe ho baseplate (95(W) x 128(L) mm), e kentsoeng ka morao ho MDE's ka liboutu tsa M3 X 25mm le 10mm standos. Liboutu tse 'ne li kentsoe masobeng a boto ea tšehetso ea Neopixel le li-standos tse kentsoeng ho hokela baseplate lihukung, masoba a 3mm a etsoa ka har'a baseplate ho ikamahanya le liboutu. Boemo le masoba a ho phunya bakeng sa sehokelo sa Edge Breakout (2 x 3mm), RTC (2 x 2mm), le switjha e netefatsang ho tloha sebakeng (20 x 40mm), ho kenya masakaneng a angle a nepahetseng a sebetsang joalo ka maoto. Lihokelo ho RTC li entsoe ka 4 Junior jumpers F/F mme RTC e sirelelitsoe ka liboutu tse 2 x M2. Lihokelo ho switjha li entsoe ka li-jumpers tse 2 tsa Junior F/M 'me sesebelisoa se kenngoa ka lesoba la 5mm. Lihokelo ho potoloho ea tšireletso ea CR bakeng sa Neopixels e entsoe ka 3 Jumpers F/F mme ho tloha ho sena ho ea ho Neopixels e nang le li-jumpers tse 3 F/M, sena se hokelloa botong ka thae ea thapo e feptjoang ka e 'ngoe ea masoba a boto.
Kenya brakete ea maoto ho baseplate ka liboutu tse 4. (Li-bolts tsa M3 tse ka tlaase bakeng sa ho khomarela baseplate li ka sebelisoa ho tšoara maoto sebakeng se nang le bolt ea 2 ka sekoting se ka tlaase sa bracket. Ho thibela ho phunya sebaka seo oache e tla lula ho eona, hokela thupa holim'a liphahlo kapa banyalani. Thepa ea motheo e se e ka kengoa holim'a liboutu tsa sekhutlo 'me ea tiisoa ka linate.

Ho bokelloa ha merero e 'maloa e menyenyane e hlahisang morero o moholoanyane. Kea ts'epa hore uena le sena le merero e amanang le eona e khahlisang.
- morero o makatsang
- Kea leboha, ke ananeloa haholo.
- Morero o motle!
- Kea leboha.
- Cool oache. Ke rata hore sena se tsamaisana le Micro:bit!
- Kea leboha, The Micro: bit e sebetsa ka mokhoa o fapaneng haholo ke e sebelisitse mererong ea ka e mengata ea oache.
