Loingseoireacht chaighdeánach saor in aisce ar orduithe os cionn $9.9
Polasaí Fillte
Glacfar le míreanna a fhillfear laistigh de 40 lá ón dáta a fhaigheann tú na hearraí. Ní féidir míreanna saincheaptha a fhillt nó a mhalartú. Ní féidir míreanna a ceannaíodh le cárta bronntanais leictreonach a fhillt; ní bhaineann aisíocaíochtaí leo.
Bronntanas Saor in Aisce
Fáilte go Roymall, do shuíomh gréasáin gairmiúil chun bronntanais ollmhargaidh préimhe a cheannach.

Nuair a cheannaíonn tú linn, ní hamháin go mbaineann tú taitneamh as táirgí ar ardchaighdeán a fheabhsaíonn do stíl mhaireachtála, ach gheobhaidh tú bronntanas saor in aisce eisiach le gach ordú a chuirfidh tú. Réidh chun iniúchadh a dhéanamh ar ár mbailiúchán agus na bronntanais foirfe a aimsiú? Déan iniúchadh ar ár rogha earraí ollmhargaidh préimhe, cuir d'ordú, agus bí ag súil le spraoi do bhronntanais saor in aisce ag teacht in éineacht le do cheannach.
Polasaí Loingseoireachta
Oibreoimid go dian chun earraí a sheachadadh chugat tar éis d'orduithe a fháil agus a chinntiú go sroicheann siad slán sábháilte. Soláthrófar sonraí seachadta i do ríomhphost deimhnithe.I bhformhór na gcásanna, déantar orduithe a phróiseáil laistigh de 2 lá. Faoi imthosca speisialta, déanfar moill air mar seo a leanas: Nuair a chuireann tú ordú Dé Sathairn, Dé Domhnaigh nó laethanta saoire poiblí, déanfar moill 2 lá air.De ghnáth, teastaíonn 5-7 lá oibre (Dé Luain go Dé hAoine) gan a bheith faoi thionchar moill eitilte nó tosca comhshaoil eile.Toisc go bhfuil ár seirbhís loingseoireachta ar fud an domhain, beidh amanna seachadta ag brath ar do shuíomh, mar sin d'fhéadfadh sé go mbeadh cúpla uair ag teastáil agus fan go foighneach má tá tú i gceantair nó tíortha iargúlta.
1. Polasaí Fillte & Malartaithe
Glacaimid le míreanna a ceannaíodh ar roymall.com amháin. Má cheannaíonn tú ónár ndáileoirí áitiúla nó miondíoltóirí eile, ní féidir leat iad a fhillt orainn.Ní ghlactar le míreanna díolacha deiridh nó bronntanais saor in aisce le fillt.Chun bheith incháilithe le fillt, ní mór do mhír a bheith gan úsáid agus sa chéad chaoi a fuair tú í. Ní mór í a bheith sa phacáistiú bunaidh freisin.Tar éis treoracha fillte a fháil uainn, déan do mhíreanna fillte a phacáistiú agus do phacáiste a scaoileadh ag oifig an phoist áitiúil nó ag seachadóir eile. Déanfaimid do mhír fillte nó malartaithe a phróiseáil laistigh de 3-5 lá oibre tar éis dúinn í a fháil. Déanfar an t-aisíoc a phróiseáil agus a chreidiúint go huathoibríoch chuig do bhunmhodh íocaíochta.Ní féidir aon fhillt nó malartuithe a ghlacadh má táirgeadh an táirge go saincheaptha, lena n-áirítear méid saincheaptha, dath saincheaptha, nó cló saincheaptha.An bhfuil cabhair bhreise uait, déan teagmháil linn. service@roymall.com nó Whatsapp: +447549870296

Feature:
Model: STM32F103C8T6
Kernel: ARM32 bit Cortexu2122-M3CPU
Size: 22.86mm x 53.34mm
Debug Mode: SWD
MCU Introduction:
1. The maximum operating frequency of 72MHz
2. Single-cycle multiply and hardware divide
3. 64k Flash program memory
4. 20k bytes SRAM
5. 2.0-3.6V power supply and I / O pins
6. On power-up, power reset (POR / PDR), programmable voltage monitor
7. 4-16MHz crystal oscillator
8. Embedded 8MHz RC oscillator
9. generates CPU clock PLL
10. Sleep Stop Standby mode
11. VBAT power for the RTC back registers
12. 37 Quick I / O ports, the I / O ports can be mapped to 16 external interrupts etc.
The PCB with STM32F103C8T6 on board works fine, can be programmed from stm programmers. It is one very serious trouble - ADC noise is very very larga, more than 5-6 units becouse of pcb desing. Be carefull with using the pcb as ADC. You can see the ADC noise on Figure.

The edges of the PCB are not burnished, but it is not a big deal - can be done easy with sandpaper.
There is one design issue with this 48 pin package - the CAN module and the USB share the same pins, that means that you can't use both in same project.

Q:
Can you please tell me this chip is original or a clone?

What kind of software do I need to program it? And surely don't advise Arduino, its shit for real world use. Little wank projects yes, but not for real ARM programming.

Arduino IDE meh but it depends on the goal, at software is powerful but also a complete pain to setup any project, for smaller projects, it's fine
I'm using it with ADC DMA, complex timer controls and more without issue

Q:
When I connect to my windows 10 PC, it can't load the driver, I do see the LEDs blinking, where can I find its driver, by default it shows unknown USB device "Device Descriptor request failed"
