Bigger circuit. Haven't found a simple implementation. Can be done, but requires a lot of wiring and increases risk of noise on power rails. Things best left to external modules: - CV-controlled CV offset module - add a switch of some that get squished or have excessive padding. ``` cd /path/to/ttrss/ git clone git@github.com:holmesrichards/precadsr.git New KiCad version; non Al panel Gerbers # Exported BOM files All-in-one module with lots of analog drum voices; based heavily on Moritz Klein's work, but with an eye towards doing it all in one module with integral chip antenna (http://ww1.microchip.com/downloads/en/DeviceDoc/60001380C.pdf Cypress EZ-BLE PRoC Module (Bluetooth Smart) 21 Pin Module Digi XBee SMT RF ESP WROOM-02 espressif esp8266ex 2.4 GHz Wi-Fi and Bluetooth combo chip, external antenna, https://www.espressif.com/sites/default/files/documentation/esp32-s3-mini-1_mini-1u_datasheet_en.pdf 2.4 GHz Wi-Fi https://www.espressif.com/sites/default/files/documentation/esp32-s2-wroom_esp32-s2-wroom-i_datasheet_en.pdf 2.4 GHz Wi-Fi and Bluetooth combo chip Single 2.4 GHz Wi-Fi and Bluetooth module, https://www.espressif.com/sites/default/files/documentation/esp32-wroom-32d_esp32-wroom-32u_datasheet_en.pdf 2.4 GHz Wi-Fi and Bluetooth module Single 2.4 GHz Wi-Fi and Bluetooth combo chip with U.FL connector, https://www.espressif.com/sites/default/files/documentation/esp32-wroom-32d_esp32-wroom-32u_datasheet_en.pdf D52M ANT SoC Module https://www.thisisant.com/assets/resources/D00001687_D52_Module_Datasheet.v.2.3_(Garmin).pdf RF SoC Radio ANT Bluetooth BLE D52 nRF52 Garmin Canada Dynastream Nordic Low Power Long Range Transceiver Module Low Power Long Range Transceiver Module Low Power Long Range Transceiver Module THT-16 (https://www.hoperf.com/data/upload/portal/20181127/5bfcbea20e9ef.pdf Low Power Long Range Transceiver Module SMD-16 (https://www.hoperf.com/data/upload/portal/20181127/5bfcbea20e9ef.pdf LoRa Low Power Long Range Transceiver Module LoRa Radio, RF, Module, http://www.hoperf.com/upload/rf/RFM69HW-V1.3.pdf 8 pin connector, PD-30, http://www.cui.com/product/resource/pd-30.pdf connector 3-pin PD-30 power DIN shielded Right-angle standard banana jack, http://www.caltestelectronics.com/images/attachments/P315100rH_drawing.pdf DEUTSCH DT header 12 pin 3-pin CPU fan 4-pin CPU fan 4-pin CPU fan JWT A3963, 3.96mm pitch Pin head connector (http://www.jwt.com.tw/pro_pdf/A3963.pdf connector JWT A3963 pinhead 7.25mm SMT Multi-directional Spring Contact (T+R), https://cdn.harwin.com/pdfs/S1941R.pdf spring contact emi emc shield Tag-Connect programming header with bottom courtyard for TC2050-NL Clip board ; https://www.tag-connect.com/wp-content/uploads/bsk-pdf-manager/TC2050-IDC-NL_Datasheet_8.pdf https://www.tag-connect.com/wp-content/uploads/bsk-pdf-manager/TC2050-CLIP_Datasheet_25.pdf Tag-Connect programming header; http://www.tag-connect.com/Materials/TC2030-IDC-NL.pdf Tag-Connect programming header; http://www.tag-connect.com/Materials/TC2030-IDC.pdf tag connect programming header pogo pins Tag-Connect programming header; http://www.tag-connect.com/Materials/TC2030-IDC-NL.pdf Tag-Connect programming header with bottom courtyard for TC2050-NL Clip board.
