This connector mates with various headers including TMMH, TMM, MTMM, MMT, TW, LTMM, ZLTMM, ESQT, TCMD, PTT, and TSH. It is packaged in a TUBE for secure handling and storage.
For complete specifications, please refer to the datasheet.
Note: Some lengths, styles, and options are non-standard and non-returnable.
All designs, specifications, and components are subject to change without notice due to ongoing technical progress.
I'm particularly impressed with how carefully the header pins are packed for the RP2350-PiZero, they arrived in perfect condition without any bent pins, which has been a persistent issue with other competitors. This attention to packaging detail really stands out.
I also received the latest A4 revision of the RP2350, which shows you maintain current inventory, that's really valuable for customers who want the most up to date components.
The delivery was quick and hassle free throughout. I'll definitely be recommending you to others!
App feedback: The discounts offered through the app are a nice bonus, but the component search function could be improved to match the ease of use on the website version. The rest of the app functions work well.
