Revising Estimated Ship Dates

by Denis Kotlar (a.k.a. prasimix)

We received an update from the company that will be supplying AC/DC converters for the BB3 peripheral modules, and it sounds like the parts we ordered will not be ready for shipment until March 20th. Unfortunately, that means we’ve had to push our estimated ship dates back to May 1st. We’ll keep you updated as we learn more.

Progress

Since our previous update, we’ve made progress in the following areas:

  • Enclosures are in the final phase; only silkscreens are missing from the front and rear panels
  • Our PCBA manufacturer has received the PCB panels; a test batch should finally start tomorrow
  • The wire harness is finished
  • We have received the cardboard boxes that we will use for shipping
  • The first 100 TFT displays have arrived
  • We are working toward closing the firmware v1.0 feature list to ensure that we have enough time for testing. We struggled a bit, recently, with the reliability of read and write access to the SD Card, which has become a vital part of the system as it handles the storage of user profiles, lists, data logs, etc. Everything now seems to be working as expected.

BB3 Enclosure & Bare Boards

A BB3 enclosure kit with a wire harness, nuts and bolts for the three core modules, a 4.3" TFT touchscreen display, an encoder knob, and an 80 mm fan. Includes a set of bare PCBs for building the three core modules (AUX-PS, MCU STM32F7, and BP3C DIB 3-slot backplane) as well as PCBs for building one DCM220 two-channel peripheral power module and two single-channel peripheral power modules (either the DCP405 or the DCP405B, as they can be assembled using the same PCB). Suitable for builders with the necessary skill, time, and patience.


$350

BB3 - Starter (Without Peripheral Modules)

A BB3 enclosure kit without bare PCBs but with fully-assembled core modules (AUX-PS, MCU STM32F7, and BP3C DIB 3-slot backplane). The Starter provides an environment for experimenters who are willing to build their own modules or who want a specific BB3 configuration (such as a six-channel BB3).


$650

BB3 - Two Channel (Full)

A BB3 starter kit and two full-featured DCP405 single-channel (40 V, 5 A) peripheral power modules, including an AC/DC power module for each. A two-channel programmable power source with advanced features: remote sensing, remote programming, a down-programmer, and additional OVP (with crowbar).


$750

BB3 - Four Channel (Full)

A BB3 starter kit, two full-featured DCP405 single-channel (40 V, 5 A) peripheral power modules, and one dual-channel DCM220 peripheral power module. Includes all three necessary AC/DC modules. This is the two-channel full kit, expanded to include two additional programmable power sources.


$179

DCP405 One Channel Module (Full)

A full-featured DCP405 single-channel (40 V, 5 A) peripheral power module with remote sensing, remote programming, a down-programmer and crowbar OVP. Includes an AC/DC module.


$125

DCM220 Two Channel Module

A DCM220 dual-channel (2 x 20 V, 4 A) peripheral power module and its AC/DC module.


$59

Cable Set

Two pairs of high quality, silicone, color marked (black-red), 1 m connecting cables; a pair of clip-on probes; and a pair of insulated crocodile clips.
