Blueline MK-7 — the documented edge controller.
A dual-core RISC-V module with 40 addressable pins, hardware crypto, and a datasheet written the way engineers actually read — spec tables first, pinouts you can copy, no marketing between you and the numbers.
Documentation set
Datasheet
Electrical characteristics, absolute maximum ratings, timing, and power domains in scan-friendly spec tables.
Pinouts
The full 40-pin map with alternate functions, drive strength, and a copyable pin table for every peripheral.
Integration guide
Bring-up from bare board: reset sequence, UART bootloader, and flashing the MK-7 over USB in under a minute.
Revision history
Every silicon and document revision, dated and diffed — including the errata you need before designing in.
Read like a drawing
This isn't a landing page dressed as docs. Every page is a drafting sheet: a title block up top, numbered sections, dimension lines under each heading, and part numbers set in mono so you can copy them straight into a BOM.
- Numeric columns right-aligned with tabular figures — scan a rating in one pass.
- Every pin name, register, and version string is a copyable mono token.
- Hazard callouts flag what the abs-max table will let you destroy.
Key specifications
| Parameter | Symbol | Min | Typ | Max (unit) |
|---|---|---|---|---|
| Core clock | f_CPU | — | 240 | 260 MHz |
| Supply voltage | VDD | 3.0 | 3.3 | 3.6 V |
| Active current | I_DD | — | 68 | 112 mA |
| Deep-sleep current | I_SLP | — | 7.5 | 12 µA |
| Operating temp | T_A | -40 | 25 | 85 ℃ |
Typical values are characterized at VDD = 3.3 V, T_A = 25 ℃. Exceeding the Max column even briefly can latch up the I/O ring — see absolute maximum ratings on the datasheet.
Peripheral map
Up to 5 Mbaud, hardware flow control on UART0/1.
Master/slave, 80 MHz, quad-line QSPI on bus 0.
Standard/Fast/Fast-Plus, clock stretching supported.
18 channels, 2 MSPS, internal reference ±0.1%.
Center-aligned, dead-time insertion for motor drive.
Hardware AES, SHA-2, and a true RNG with entropy pool.
Latest revisions
The MK-7 silicon and its documentation move together. Check the revision block before you design in — errata land here first.
Full historyTrusted on the bench
“First datasheet in years where I found the abs-max ratings in under ten seconds. The pin table copies clean into KiCad.”
“The revision page saved a spin. ERR-118 was flagged the day we picked the part — we routed around it before layout.”
“No hero video, no cookie wall, just numbers. Exactly what documentation should be. My students learn to read a datasheet here.”
Start with the datasheet. End with working silicon.
Full electrical characteristics, the complete pin map, and every revision — open, copyable, and free of marketing.
